[orc-rt] Reconcile check-rt-process-info changes. (#225592)
3648582c0a41 was supposed to make this test more generic, but
accidentally removed it instead.
Reconcile the dropped changes with 3648582c0a41, which added page-size
checking.
[RISCV] Expand scalar FP undef/poison to 0.0 with F extension. (#225567)
This ensures the undef/poison value is always nan-boxed. This is
important if the value ends up being used by a freeze. If the value
isn't properly nan-boxed, it will be treated as a nan in FP contexts
regardless of its lower bits. If the freeze is also cast to an integer,
the lack of nan-boxing will be noticed and the integer will see the real
value of the lower bits.
Fixes #225455.
[orc-rt] Add Windows page size detection (#224520)
Adds Windows page size detection for ORC-RT using GetSystemInfo.
Also updates the process-info regression coverage into a single test

[AMDGPU] Port Atomic-Optimizer to use Wave Reduction Intrinsics (#211757)
Currently the atomic optimizer creates reductions via intrinsics,
and introduces new control flows.
Replace this sub-target dependent logic with the existing
wave reduction intrinsics, which get lowered in the backend.
This patch ports the uniform-value and divergent-no-return-value cases.
To port the divergent-with-return-value cases, additional scan intrinsics
will need to be added.
[lld] Add -z mark-plt support for X86_64 (#206002)
Add option [no]mark-plt to enable it. Dynamic linker can change PLT
entries with JMPABS instruction on supported targets.

[libc++] Build GoogleBenchmark directly from Lit (#224192)
Previously, we would build GoogleBenchmark against the just-built
library, not against the library being tested. When testing historical
versions of libc++ or other standard libraries, this breaks. So instead
of building Google Benchmark against the just-built library in CMake, do
it from Lit as part of the test suite's configuration.
I'm not a huge fan of using Lit as a poor man's build system and we
should make the CMake test suite self-contained, however this is a step
in the right direction and it removes a major coupling between the test
suite and the regular libc++ build.
[libc++] Pin down the OS version of macOS runners (#225536)
Otherwise, we sometimes end up using runners that don't have Xcode 26.5
on them. Pinning this allows bumping the version explicitly when we are
ready to.
