Previously, -W(all-)missed-specs was created with 'NoReason',
so no information about the flag was printed along with the warning.
Now, -Wall-missed-specs is listed as the Reason if it was set,
otherwise -Wmissed-specs is listed as the reason.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Generate straightline code for inline array allocation
GHC has an optimization for allocating arrays when the size is
statically known -- it'll generate the code allocating and initializing
the array inline (instead of a call to a procedure from
`rts/PrimOps.cmm`).
However, the generated code uses a loop to do the initialization. Since
we already check that the requested size is small (we check against
`maxInlineAllocSize`), we can generate faster straightline code instead.
This brings about 15% improvement for `newSmallArray#` in my testing and
slightly simplifies the code in GHC.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Fix #16500: look for interface files in -hidir flag in OneShot mode
We are currently ignoring options set in the hiDir field of hsc_dflags
when looking for interface files while compiling in OneShot mode. This
is inconsistent with the behaviour of other directory redirecting fields
(such as objectDir or hieDir). It is also inconsistent with the
behaviour of compilation in CompManager mode (a.k.a `ghc --make`) which
looks for interface files in the directory set in hidir flag. This
changes Finder.hs so that we use the value of hiDir while looking for
interface in OneShot mode.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Make `singleConstructor` cope with pattern synonyms
Previously, `singleConstructor` didn't handle singleton `COMPLETE` sets
of a single pattern synonym, resulting in incomplete pattern warnings
in #15753.
This is fixed by making `singleConstructor` (now named
`singleMatchConstructor`) query `allCompleteMatches`, necessarily making
it effectful. As a result, most of this patch is concerned with
threading the side-effect through to `singleMatchConstructor`.
Unfortunately, this is not enough to completely fix the original
reproduction from #15753 and #15884, which are related to function
applications in pattern guards being translated too conservatively.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">codegen: fix memset unroll for small bytearrays, add 64-bit sets
Fixes #16052
When the offset in `setByteArray#` is statically known, we can provide
better alignment guarantees then just 1 byte.
Also, memset can now do 64-bit wide sets.
The current memset intrinsic is not optimal however and can be
improved for the case when we know that we deal with
(baseAddress at known alignment) + offset
For instance, on 64-bit
`setByteArray# s 1# 23# 0#`
given that bytearray is 8 bytes aligned could be unrolled into
`movb, movw, movl, movq, movq`; but currently it is
`movb x23` since alignment of 1 is all we can embed into MO_Memset op.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Hadrian: fix library install paths in bindist Makefile (#16498)
GHC now works out-of-the-box (i.e. without any wrapper script) by
assuming that @bin@ and @lib@ directories sit next to each other. In
particular, its RUNPATH uses $ORIGIN-based relative path to find the
libraries.
However, to be good citizens we want to support the case where @bin@ and
@lib@ directories (respectively BINDIR and LIBDIR) don't sit next to
each other or are renamed. To do that the install script simply creates
GHC specific @bin@ and @lib@ siblings directories into:
LIBDIR/ghc-VERSION/{bin,lib}
Then it installs wrapper scripts into BINDIR that call the appropriate
programs into LIBDIR/ghc-VERSION/bin/.
The issue fixed by this patch is that libraries were not installed into
LIBDIR/ghc-VERSION/lib but directly into LIBDIR.

Using `ghc-prim <= 0.6.1` is somewhat dodgy from a PVP point of view,

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">removing x87 register support from native code gen
* simplifies registers to have GPR, Float and Double, by removing the SSE2 and X87 Constructors
* makes -msse2 assumed/default for x86 platforms, fixing a long standing nondeterminism in rounding
behavior in 32bit haskell code
* removes the 80bit floating point representation from the supported float sizes
* theres still 1 tiny bit of x87 support needed,
for handling float and double return values in FFI calls wrt the C ABI on x86_32,
but this one piece does not leak into the rest of NCG.
* Lots of code thats not been touched in a long time got deleted as a
consequence of all of this
all in all, this change paves the way towards a lot of future further
improvements in how GHC handles floating point computations, along with
making the native code gen more accessible to a larger pool of contributors.

When -a or --test-accept is passed, and if one runs the 'test' target, then
any test failing because of mismatching output and which is not expected to
fail will have its expected output adjusted by the test driver, effectively
considering the new output correct from now on.
When this flag is passed, hadrian's 'test' target becomes sensitive to the
PLATFORM and OS environment variable, just like the Make build system:
- when the PLATFORM env var is set to "YES", when accepting a result, accept it
for the current platform;
- when the OS env var is set to "YES", when accepting a result, accept it
for all wordsizes of the current operating system.
This can all be combined with `--only="..."` and `TEST="..." to only accept
the new output of a subset of tests.

This patch adds an Hadrian target "binary-dist-dir". Compared to
"binary-dist", it only builds a binary distribution directory without
creating the Tar archive. It makes the use/test of the bindist
installation script easier.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Add a safeguard to Core Lint
Lint returns a pair (Maybe a, WarnsAndErrs). The Maybe monad
allows to handle an unrecoverable failure.
In case of such a failure, the error should be added to the second
component of the pair. If this is not done, Lint will silently
accept bad programs. This situation actually happened during
development of linear types. This adds a safeguard.

Directives in .ghci files in the current directory ("local .ghci")
can be overridden by global files. Change the order in which the
configs are loaded: global and $HOME/.ghci first, then local.
Also introduce a new field to GHCiState to control whether local
.ghci gets sourced or ignored. This commit does not add a way to
set this value (a subsequent commit will add this), but the .ghci
sourcing routine respects its value.

Add the ':set local-config { source | ignore }' setting to control

directive can be set in global config or $HOME/.ghci, which are
processed before local .ghci files.
The default is "source", preserving current behaviour.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">asm-emit-time IND_STATIC elimination
When a new closure identifier is being established to a
local or exported closure already emitted into the same
module, refrain from adding an IND_STATIC closure, and
instead emit an assembly-language alias.
Inter-module IND_STATIC objects still remain, and need to be
addressed by other measures.
Binary-size savings on nofib are around 0.1%.
