The main purpose is to create tests for minimal app (hello world and its variations, i.e. unicode used) distribution size metric.
Many platforms support distribution in compressed form via gzip. It would be nice to collect information on how much size is taken by the executional bundle for each platform at minimal edge case.
2 groups of tests are added:
1. We extend javascript backend size tests with gzip-enabled versions for all cases where an optimizing compiler is used (for now it is google closure compiler).
2. We add trivial hello world tests with gzip-enabled versions for all other platforms at CI pipeline where no external optimizing compiler is used.

- beef61351b240967b49169d27a9a19565cf3c4af enabled the use of
MO_Add/MO_Sub for 64-bit operations in the C and LLVM backends
- 6755d833af8c21bbad6585144b10e20ac4a0a1ab did the same for the x86 NCG
backend
However we store some literal values as `Int` in the compiler. As a
result, some Cmm optimizations transformed target 64-bit literals into
compiler `Int`. If the compiler is 32-bit, this leads to computing with
wrong literals (see #24893 and #24700).
This patch disables these Cmm optimizations for 32-bit compilers. This
is unsatisfying (optimizations shouldn't be compiler-word-size
dependent) but it fixes the bug and it makes the patch easy to backport.
A proper fix would be much more invasive but it shall be implemented in
the future.

Need to extend JSC externs with Emscripten RTS definitions to avoid

Fix #25138
Some recompilation avoidance tests now fail. This is tracked with the
other instances of this failure in #23013. My hunch is that they were
working by chance when we used the emcc linker.

We build these two packages as regular boot library dependencies rather
than using the `in-ghc-tree` flag to include the source files into the haddock
executable.
The `in-ghc-tree` flag is moved into haddock-api to ensure that haddock built
from hackage can still find the location of the GHC bindist using `ghc-paths`.
Addresses #24834
This causes a metric decrease under non-release flavours because under these
flavours libraries are compiled with optimisation but executables are not.
Since we move the bulk of the code from the haddock executable to the
haddock-api library, we see a metric decrease on the validate flavours.

At GhcRn stage, in isIrrefutableHsPat we only looked up data constructors
in the RdrEnv, which meant that we lacked fallibility information for
out-of-scope constructors (which can arise from Template Haskell splices).
Instead, we use 'lookupGREInfo', which looks up the information in
the type environment. This was the correct function to call all along,
but was not used in 572fbc44 due to import cycle reasons. The appropriate
functions, 'irrefutableConLike{Rn,Tc}' have been moved to 'GHC.Rename.Env',
which avoids import cycles.
Fixes #25164

- Rename LoadedBCOs into LazyBCOs
- Bundle SptEntries with CompiledByteCode and removed [SptEntry] field
from the BCOs constructor
- Rename Linkable's LM constructor into Linkable: in the past we had LM
and LP for Module and Package, now we only have the former.
- Rename Unlinked into LinkablePart (and linkableUnlinked into
linkableParts)
- Use NonEmpty to encode invariant in Linkable's linkableParts type
- Add helpers: linkableLibs, linkableBCOs, etc.
- Add documentation
- Remove partial nameOfObject
- Rename nameOfObject_maybe into linkablePartPath
- Rename byteCodeOfObject into linkablePartAllBCOs.
- Refactor linkablePartAllBCOs to avoid a panic if a LazyBCO has a C
stub. Document the fact that LazyBCOs are returned in this case
(contrary to linkableBCOs which only returns non-lazy ones)
Refactoring done while trying to understand how to adapt the linker code
to support the JS backend too (cf #24886).

This squashed commit adds support for exportable named defaults, the accepted
GHC proposal at https://github.com/ghc-proposals/ghc-proposals/pull/409
The proposal extends the Haskell '98 declarations
default (Int, Double)
which were implicitly always applying to Num class alone, to allow specifying
an arbitrary single-parameter class:
default IsString (Text, String)
The effect of this declaration would be to eliminate the ambiguous type errors
around string literals when OverloadedStrings extension is active. The
declaration by itself has effect only in its module, so the proposal also adds
the ability to export class defaults:
module MyModule (default IsIstring)
Once the language extension is published and established, we can consider using
it in base and other libraries.
See Note [Named default declarations] in GHC.Tc.Gen.Default
for implementation details.

This MR revised the crucial kick-out criteria in the constraint solver.
Ticket #24984 showed an example in which
* We were kicking out unnecessarily
* That gave rise to extra work, of course
* But it /also/ led to exponentially-sized coercions due to lack
of sharing in coercions (something we want to fix separately #20264)
This MR sharpens up the kick-out criteria; specifially in (KK2) we look
only under type family applications if (fs>=fw).
This forced me to understand the existing kick-out story, and I ended
up rewriting many of the careful Notes in GHC.Tc.Solver.InertSet.
Especially look at the new `Note [The KickOut Criteria]`
The proof of termination is not air-tight, but it is better than before,
and both Richard and I think it's correct :-).

This patch removes the -fasm flag from test ways, except ways like
optasm that explicitly state they are meant to be compiled with NCG

the precense of -fasm can cause stderr mismatches like this when GHC
is configured with the unregisterised backend:

This commit fixes isMinTTY.h casing in isMinTTY.c that's compiled for

are case-insensitive by default, it does cause a compilation warning
with recent versions of clang, so we might as well fix the casing:

This data is used alongside Core bindings to reconstruct intermediate
build products when linking Template Haskell splices with bytecode.
Since foreign stubs and files are generated in the pipeline, they were
lost with only Core bindings stored in interfaces.
The interface codec type `IfaceForeign` contains a simplified
representation of `ForeignStubs` and the set of foreign sources that
were manually added by the user.
When the backend phase writes an interface, `mkFullIface` calls
`encodeIfaceForeign` to read foreign source file contents and assemble
`IfaceForeign`.
After the recompilation status check of an upstream module,
`initWholeCoreBindings` calls `decodeIfaceForeign` to restore
`ForeignStubs` and write the contents of foreign sources to the file
system as temporary files.
The restored foreign inputs are then processed by `hscInteractive` in
the same manner as in a regular pipeline.
When linking the stub objects for splices, they are excluded from suffix
adjustment for the interpreter way through a new flag in `Unlinked`.
For details about these processes, please consult Note [Foreign stubs
and TH bytecode linking].

a.out is a configure script byproduct. It was mistakenly checked into
the tree in !13118. This patch removes it, and include it in
.gitignore to prevent a similar error in the future.

openat/fstatat/unlinkat/dup are now used in the recent release of the
`directory` and `file-io` packages.
As such, these functions are (indirectly) used in the following tests
one we'll bump the `directory` submodule (see !13122):

- jsOptimizer
- T20509

The primary reason for this bump is to fix the warning from `ghc-pkg
check`:
```
Warning: include-dirs: /data/home/ubuntu/.ghcup/ghc/9.6.2/lib/ghc-9.6.2/lib/../lib/aarch64-linux-ghc-9.6.2/directory-1.3.8.1/include doesn't exist or isn't a directory
```
This also requires adding the `file-io` package as a boot library (which
is discussed in #25145)

We are producing bindists where the target triple is
aarch64-alpine-linux
when it should be
aarch64-unknown-linux
This is because the bootstrapped compiler originally set the target
triple to `aarch64-alpine-linux` which is when propagated forwards by
setting `bootstrap_target` from the bootstrap compiler target.
In order to break this chain we explicitly specify build/host/target for
aarch64-alpine.
This requires a new configure flag `--enable-ignore-` which just
switches off a validation check that the target platform of the
bootstrap compiler is the same as the build platform. It is the same,
but the name is just wrong.
These commits can be removed when the bootstrap compiler has the correct
target triple (I looked into patching this on ci-images, but it looked
hard to do correctly as the build/host platform is not in the settings
file).

This is a reinterpretation of GHC Proposal #409 that avoids a breaking
change introduced in fa0dbaca6c "Implements the Exportable Named Default proposal"
Consider a module M that has no explicit export list:
module M where
default (Rational)
Should it export the default (Rational)?
The proposal says "yes", and there's a test case for that:
default/DefaultImport04.hs
However, as it turns out, this change in behavior breaks existing
programs, e.g. the colour-2.3.6 package can no longer be compiled,
as reported in #25206.
In this patch, we make implicit exports of defaults conditional on
the NamedDefaults extension. This fix is unintrusive and compliant
with the existing proposal text (i.e. it does not require a proposal
amendment). Should the proposal be amended, we can go for a simpler
solution, such as requiring all defaults to be exported explicitly.
Test case: testsuite/tests/default/T25206.hs

The `asBox` function is intended to store exactly the closure which the
user passes to it. Placing a cost centre on asBox introduces a thunk,
which violates this expectation and can change the result of using asBox
when profiling is enabled.
See #25212 for more details and ample opportunity to discuss if this is
a bug or not.

Fix 1: If a cost centre contained CAF then the normalisation was

Fix 2: "no location info" contain a space, which messed up the next
