CmmToLlvm: Don't aliasify builtin LLVM variables

Our aliasification logic would previously turn builtin LLVM variables
into aliases, which apparently confuses LLVM. This manifested in
initializers failing to be emitted, resulting in many profiling failures
with the LLVM backend.

Fixes #22019.

run_ci: remove monoidal-containers

Fixes #21492

MonoidalMap is inlined and used to implement Variables, as before.

The top-level value "jobs" is reimplemented as a regular Map, since it
doesn't use the monoidal union anyway.

Fix #21979 - compact-share failing with -O

I don't have good reason to believe the optimization level should affect
if sharing works or not here. So limit the test to the normal way.

Implement Response File support for HPC

This is an improvement to HPC authored by Richard Wallace
(https://github.com/purefn) and myself. I have received permission from
him to attempt to upstream it. This improvement was originally
implemented as a patch to HPC via input-output-hk/haskell.nix:
https://github.com/input-output-hk/haskell.nix/pull/1464

Paraphrasing Richard, HPC currently requires all inputs as command line arguments.
With large projects this can result in an argument list too long error.
I have only seen this error in Nix, but I assume it can occur is a plain Unix environment.

This MR adds the standard response file syntax support to HPC. For
example you can now pass a file to the command line which contains the
arguments.

```
hpc @response_file_1 @response_file_2 ...

The contents of a Response File must have this format:
COMMAND ...

example:
report my_library.tix --include=ModuleA --include=ModuleB
```

Updates hpc submodule

ghc-heap: Fix decoding of TSO closures

An extra field was added to the TSO structure in 6d1700b6 but the
decoding logic in ghc-heap was not updated for this new field.

Fixes #22046

driver: Honour -x option

The -x option is used to manually specify which phase a file should be
started to be compiled from (even if it lacks the correct extension). I
just failed to implement this when refactoring the driver.

In particular Cabal calls GHC with `-E -cpp -x hs Foo.cpphs` to
preprocess source files using GHC.

I added a test to exercise this case.

Fixes #22044

Be more careful in chooseInferredQuantifiers

This fixes #22065. We were failing to retain a quantifier that
was mentioned in the kind of another retained quantifier.

Easy to fix.

compiler: Drop --build-id=none hack

Since 2011 the object-joining implementation has had a hack to pass
`--build-id=none` to `ld` when supported, seemingly to work around a
linker bug. This hack is now unnecessary and may break downstream users
who expect objects to have valid build-ids. Remove it.

Closes #22060.

Make ru_fn field strict to avoid retaining Ids

It's better to perform this projection from Id to Name strictly so we
don't retain an old Id (hence IdInfo, hence Unfolding, hence everything
etc)

Force unfoldings when they are cleaned-up in Tidy and CorePrep

If these thunks are not forced then the entire unfolding for the binding
is live throughout the whole of CodeGen despite the fact it should have
been discarded.

haddock docs: Fix links from identifiers to dependent packages

When implementing the base_url changes I made the pretty bad mistake of
zipping together two lists which were in different orders. The simpler
thing to do is just modify `haddockDependencies` to also return the
package identifier so that everything stays in sync.

Fixes #22001

Revert "Refactor SpecConstr to use treat bindings uniformly"

This reverts commit 415468fef8a3e9181b7eca86de0e05c0cce31729.

This refactoring introduced quite a severe residency regression (900MB
live from 650MB live when compiling mmark), see #21993 for a reproducer
and more discussion.

hadrian: Fix bootstrapping with ghc-9.4

The error was that we were trying to link together

    containers from boot package library (which depends template-haskell in boot package library)
    template-haskell from in-tree package database

So the fix is to build containers in stage0 (and link against template-haskell built in stage0).

Fixes #21981

Added pprType with precedence argument, as a prerequisite to fix issues #21723 and #21942.

* refines the precedence levels, adding `qualPrec` and `funPrec` to better control parenthesization
* `pprParendType`, `pprFunArgType`, and `instance Ppr Type` all just call `pprType` with proper precedence
* `ParensT` constructor is now always printed parenthesized
* adds the precedence argument to `pprTyApp` as well, as it needs to keep track and pass it down
* using `>=` instead of former `>` to match the Core type printing logic
* some test outputs have changed, losing extraneous parentheses

hadrian: Don't duplicate binaries on installation

Previously we used `install` on symbolic links, which ended up
copying the target file rather than installing a symbolic link.

Fixes #22062.

Fix GHCis interaction with tag inference.

I had assumed that wrappers were not inlined in interactive mode.
Meaning we would always execute the compiled wrapper which properly
takes care of upholding the strict field invariant.
This turned out to be wrong. So instead we now run tag inference even
when we generate bytecode. In that case only for correctness not
performance reasons although it will be still beneficial for runtime
in some cases.

I further fixed a bug where GHCi didn't tag nullary constructors
properly when used as arguments. Which caused segfaults when calling
into compiled functions which expect the strict field invariant to
be upheld.

Fixes #22042 and #21083
