• Removed compiler bug workarounds.
  • VSO-1881472 "/clr C++20 x86 System.AccessViolationException with atomic<with_padding_bits<8>>".
  • VSO-1885306 "warning C5039 shouldn't be emitted when an extern "C" function is marked noexcept(false)".
    • I manually verified this fix.
  • DevCom-10138792 VSO-1611566 "Bogus warning C4455: 'operator ""s': literal suffix identifiers that do not start with an underscore are reserved".
    • This bug remains active, but I notified the compiler dev it's assigned to that it appears to be fixed.
  • Remove libcxx skips for std/containers/sequences/vector.bool/move.pass.cpp.
    • We never analyzed this failure, but a compiler bug was fixed, yay!
  • Remove an _MSVC_INTERNAL_TESTING workaround in P0226R1_math_special_functions.
    • This test coverage was enabled for GitHub, and for static linking internally, but was skipped for dynamic linking internally while we waited for the 17.6 Preview 2 redist there. That's ancient history now!
  • EDG common_reference_t started behaving correctly in 17.9 Preview 1, so we can enable VSO_0000000_type_traits test coverage for GitHub.
    • We'll need to skip it internally until EDG is updated there. I'm skipping it, instead of continuing to assert the incorrect behavior, to avoid blocking the EDG update. This blocked MSVC-PR-509221 on 2023-11-06, but I didn't notice until now. 🙀
• Infrastructure improvements:
  • Updated dependencies.
    • Updated build compiler to VS 2022 17.9 Preview 1 (now required).

Other commits:

• Update to PowerShell 7.3.9 when building the pool.
• New pool.
• README drive-by: Update URL for git clone.
  • I noticed that git emitted a message about another remote moving from username/STL to username/STL.git. While I didn't observe that for my microsoft remote, it still seems better to use the exact URL that GitHub's Code > Clone displays.

x86chk stlimport passed internally, verifying the /clr x86 workaround removal and the _MSVC_INTERNAL_TESTING changes.
