[libc++][NFC] Avoid checking that string::iterator is a contiguous iterator (#178636)
`__is_continuation` is only used in contexts where we already know that
the argument is a contiguous iterator. However, due to the context in
which it is used, we check it as soon as the header is included. The
`contiguous_iterator` check is quite expensive (~12ms on my system), so
avoiding it reduces compile times for quite a few headers, including
`<vector>`.
[Clang] speed up -Wassign-enum via enumerator caching (#176560)
Fixes #176454
---
This patch addresses a performance issue in `-Wassign-enum` where
enumerator values were repeatedly rebuilt and sorted for each assignment
check, leading to excessive compile-time overhead for large enums.
The following charts demonstrate the benchmark results before and after
caching enumerator values

clang: add test for C2y n3605 (#178479)
Add a test for N3605: Generic replacement (v. 2 of quasi-literals)
The paper clarifies existing behavior of _Generic selection and
parenthesis. This PR adds tests along the same lines and mark the
feature as supported.
clang: improve lit testing docs (#178244)
The LLVM Integrated Tester now generates an "easy to use" script to run
clang tests. It is no longer needed to pass all of the commandline
arguments to it. This PR simplifies the documentation a little by
removing the unneeded commandline arguments and adding a link to the lit
man page.
py-psutil: updated to 7.2.2
7.2.2
**Enhancements**
- 2705_: [Linux]: `Process.wait()`_ now uses ``pidfd_open()`` + ``poll()`` for
waiting, resulting in no busy loop and faster response times. Requires
Linux >= 5.3 and Python >= 3.9. Falls back to traditional polling if
unavailable.
- 2705_: [macOS], [BSD]: `Process.wait()`_ now uses ``kqueue()`` for waiting,
resulting in no busy loop and faster response times.
**Bug fixes**
- 2701_, [macOS]: fix compilation error on macOS < 10.7. (patch by Sergey
Fedorov)
- 2707_, [macOS]: fix potential memory leaks in error paths of
`Process.memory_full_info()` and `Process.threads()`.

py-psleak: updated to 0.1.5
A testing framework for detecting memory leaks and unclosed resources
created by Python functions, particularly those implemented in C
or other native extensions.
[AMDGPU] Add test for amdgcn.if/else per-output uniformity (NFC)
Add a test to document the current behavior of uniformity analysis for
amdgcn.if and amdgcn.else intrinsics. Currently both outputs are marked
divergent regardless of input uniformity.
IR: Add stub LLVMCreateDenormalFPEnvAttribute to C API
This is a staging commit for #174293 to avoid an intermediate
break of the mesa build when committed. Implement just enough
of the API in terms of the old attributes to avoid breaking
the mesa use. #174293 will then implement the full API in terms
of the new attribute.
