This also fixes test failures in the clang-cl build configs that started
a couple days ago. It seems like the failures were triggered by an update
to the base image on the Github provided runners.
There were failures in test/libcxx/system_reserved_names.gen.py, due to
an issue in an Clang intrinsics header (avx512fp16intrin.h); this issue
was observed and fixed for Clang 19 in 6f04f46927c. The test does
#define A SYSTEM_RESERVED_NAME
which clashes with a parameter with the name `A` in that header.
By upgrading the toolchain to Clang 19, we get fixed version of this
intrinsics header.
Also update the llvm-mingw toolchains to a version with Clang 19.1.7.

# This file defines pre-commit CI for libc++, libc++abi, and libunwind (on Github).
|
|
#
|
|
# We split the configurations in multiple stages with the intent of saving compute time
|
|
# when a job fails early in the pipeline. This is why the jobs are marked as `continue-on-error: false`.
|
|
# We try to run the CI configurations with the most signal in the first stage.
|
|
#
|
|
# Stages 1 & 2 are meant to be "smoke tests", and are meant to catch most build/test failures quickly and without using
|
|
# too many resources.
|
|
# Stage 3 is "everything else", and is meant to catch breakages on more niche or unique configurations.
|
|
#
|
|
# Therefore, we "fail-fast" for any failures during stages 1 & 2, meaning any job failing cancels all other running jobs,
|
|
# under the assumption that if the "smoke tests" fail, then the other configurations will likely fail in the same way.
|
|
# However, stage 3 does not fail fast, as it's more likely that any one job failing is a flake or a configuration-specific
