Migrate `Finder` component to `OsPath`, fixed #24616
For each module in a GHCi session, we keep alive one `ModLocation`.
A `ModLocation` is fairly inefficiently packed, as `String`s are
expensive in memory usage.
While benchmarking the agda codebase, we concluded that we keep alive
around 11MB of `FilePath`'s, solely retained by `ModLocation`.
We provide a more densely packed encoding of `ModLocation`, by moving
from `FilePath` to `OsPath`. Further, we migrate the full `Finder`
component to `OsPath` to avoid unnecessary transformations.
As the `Finder` component is well-encapsulated, this requires only a
minimal amount of changes in other modules.
We introduce pattern synonym for 'ModLocation' which maintains backwards
compatibility and avoids breaking consumers of 'ModLocation'.

compiler: emit NaturallyAligned when element type & index type are the same width
This commit fixes a subtle mistake in alignmentFromTypes that used to
generate Unaligned when element type & index type are the same width.

Implement Or Patterns (#22596)
This commit introduces a new language extension, `-XOrPatterns`, as described in
GHC Proposal 522.
An or-pattern `pat1; ...; patk` succeeds iff one of the patterns `pat1`, ...,
`patk` succeed, in this order.
See also the summary `Note [Implmentation of OrPatterns]`.

compiler/ghci/rts: remove stdcall support completely
We have formally dropped i386 windows support (#18487) a long time
ago. The stdcall foreign call convention is only used by i386 windows,
and the legacy logic around it is a significant maintenance burden for
future work that adds arm64 windows support (#24603). Therefore, this
patch removes stdcall support completely from the compiler as well as
the RTS (#24883):
- stdcall is still recognized as a FFI calling convention in Haskell
syntax. GHC will now unconditionally emit a warning
(-Wunsupported-calling-conventions) and treat it as ccall.
- Apart from minimum logic to support the parsing and warning logic,
all other code paths related to stdcall has been completely stripped
from the compiler.
- ghci only supports FFI_DEFAULT_ABI and ccall convention from now on.
- FFI foreign export adjustor code on all platforms no longer handles
the stdcall case and only handles ccall from now on.
- The Win32 specific parts of RTS no longer has special code paths for
stdcall.
This commit is the final nail on the coffin for i386 windows support.
Further commits will perform more housecleaning to strip the legacy
code paths and pave way for future arm64 windows support.

testsuite: adapt the testsuite for stdcall removal
This patch adjusts test cases to handle the stdcall removal:
- Some stdcall usages are replaced with ccall since stdcall doesn't
make sense anymore.
- We also preserve some stdcall usages, and check in the expected
warning messages to ensure GHC always warn about stdcall usages
(-Wunsupported-calling-conventions) as expected.
- Error code testsuite coverage is slightly improved,
-Wunsupported-calling-conventions is now tested.
- Obsolete code paths related to i386 windows are also removed.

hadrian: improve user settings documentation
This patch adds minor improvements to hadrian user settings documentation:
- Add missing `ghc.cpp.opts` case
- Remove non-existent `cxx` case
- Clarify `cc.c.opts` also works for C++, while `cc.deps.opts` doesn't
- Add example of passing configure argument to autoconf packages

hadrian: add +text_simdutf flavour transformer to allow building text with simdutf
This patch adds a +text_simdutf flavour transformer to hadrian to
allow downstream packagers and users that build from source to opt-in
simdutf support for text, in order to benefit from SIMD speedup at
run-time. It's still disabled by default for the time being.

autoconf: normalize paths of some build-time dependencies on Windows
This commit applies path normalization via cygpath -m to some
