[libc][MacOS] Enable wchar conversion and rpc_server (#191065)
Originally the wchar conversion was disabled due to MacOS not providing
uchar.h. We only needed it for char32_t so this PR just provides it
directly from our headers on MacOS. This also fixes fwrite_unlocked not
being available on MacOS which is needed for rpc_server.h.
[SPIR-V] Drop initializer for Import linkage type globals (#190942)
Per SPIR-V spec, variable with Import linkage must not have initializer
Fix corresponding spirv-val error:
```
error: A module-scope OpVariable with initialization value cannot be marked with the Import Linkage Type.

[libc++] Use Fuchsia futex operations (#133571)
The basic futex operations have always been available on Fuchsia.
Wire them up to properly support C++20 atomic notify_*/wait.
[UpdateTestChecks] Add --filter/--filter-out support to update_mir_test_checks.py
These options were already accepted by the script but silently ignored.
This patch makes them functional, consistent with update_llc_test_checks.py.

[CIR][NFC] Simplify LexicalScope::cleanup() (#191034)
The LexicalScope::cleanup() function contained a lot of logic that had
been copied from the classic codegen version of this function to
properly handle branching through cleanup blocks. Since CIR cleanups are
no longer based on blocks and branches, this had become dead code. This
change simplifies the function accordiningly. This also removes the
LexicalScope::getCleanupBlock() function which is no longer called, and
the LexicalScope::createCleanupBlock() and
LexicalScope::getOrCreateCleanupBlock() functions which weren't called
even before this change.

[clang][Modules] Diagnosing Module Redefinition Across ModuleMaps (#190085)
This PR enhances the module redefinition diagnostic to cover a very
specific case.
1. A module, say `B`, is discovered first during header search. In other
words, it is declared in a modulemap that shows up first on the search
paths.
2. `B` is declared again in a different modulemap, which shows up in a
later search path, and the compiler discovers `B` again when it is
searching for a different named module.
See the two tests added for examples of this specific scenario. Under
such a scenario, the compiler now reports the module redefined error.
Note that we are not diagnosing duplicating module definitions globally,
because that requires looking through all search paths and loading all
module maps, which is too expensive.

[lldb/Target] Unify frame provider descriptor and chain IDs (#190712)
Replace the two separate ID systems for frame providers — hash-based
descriptor IDs in Target and sequential chain IDs in Thread — with a
single monotonically increasing counter in Target.
Provider IDs are now assigned by
Target::AddScriptedFrameProviderDescriptor
and used directly as the chain ID in Thread, so
RegisterScriptedFrameProvider
returns the same ID used by 'bt --provider'. Also add duplicate
detection to
emit a warning when registering a provider with the same class name and
arguments twice.

[MLIR][XeGPU] TensorDesc Type support generic DistributeLayout instead of Layout (#190401)
This PR allows TensorDesc to support slice layout, not just plain
layout.
