The ARM github actions runners now run on Windows 11 10.0.26100,
which no longer support executing armv7 binaries. (Previously they
were running Windows 11 10.0.22631.)
This allows specifying either a commit or a branch in the same
field, allowing simplifying both the workflow inputs, and
the expressions for passing commit/branch to both
dawidd6/action-download-artifact and actions/checkout.
This new option is available since
https://github.com/dawidd6/action-download-artifact/pull/329.
As the branch field has a default value "master", this default
not only applies when the dialog box for starting the manual
workflow is presented. But even if the prefilled branch field
is cleared, the default value also gets substituted when submitting.
In this case, when the commit and branch fields are mutually
exclusive, we can't easily have a default. Instead change the
uses of the fields, ignoring the branch field if the commit field
is filled.
If the dawidd6/action-download-artifact action would support
specifying either a commit or a branch in the same field, like
actions/checkout does, we wouldn't need this distinction at all;
this request is tracked upstream at
https://github.com/dawidd6/action-download-artifact/issues/242.
This requires setting CMAKE_CXX_COMPILER_TARGET manually; the LLVM
build system infers the wrong architecture when CMake is an
x86_64 binary.
(The wrong inferred architecture doesn't affect building libcxx,
but the wrong architecture gets passed as --target= parameter
when running the tests.)
Since 9c67ae861ccb0312fc680414a8441892d169d14a in llvm-project
(May 9th), these tests should pass on aarch64 too.

This matches what 28851edf164a337c334755ae33fd58f03cffd5a2 in
llvm-project did.
When setting up the built libcxx files for testing, the built
files are installed into a temporary test root, and the install of
them litters the build log with mostly uninteresting output.
This skips test that use a lot of memory. In particular, there's
one test that would use up to 6.8 GB of memory, while the GitHub
Actions runners only have 8 GB of memory available.
This parameter was added in 122064a6303eb9c06e0af231f5a4ce145d9a2e67
in the llvm-project main branch, and backported to 17.x in
aa03fba83b17bbfcd9ed869efed2818b503875d6.
Ninja isn't documented as one of the tools provided by the CI runner
images, but it used to be available implicitly installed before
in the windows-2022 images. Since the 20230918.1.0 image update,
it no longer is available out of the box; see
https://github.com/actions/runner-images/issues/8343.
