to avoid getting OOM killed. It's been happening regularly recently. We
need to have a high number of GitHub Actions runners simultaneously
active, otherwise the hardware ends up underutilized. But with zig build
running in parallel now, this sometimes results in memory usage spikes
that have been causing the runner to get killed.
This number is the total physical memory (126G) divided by the number of
runners we have active (6).
This reverts commit a34752c941c81e600c56670abb612fc86d0a2b73.
With #15277 merged, the macOS CI will still run the self-hosted x86_64
tests even with -Dskip-non-native. This was the main motivation for the
commit.
It would be nice to keep this flag enabled, however, we don't have
enough CI computing power, and the macOS CI lags behind with these extra
tests enabled.

I find myself quite often creating ReleaseSafe builds and putting them
to production for certain experiments:
- Debug info are for stack traces. An ongoing example where those would
help is #14815.
- Safety checks would have saved a couple of mine and @kubkon's hours in
#15098.
This is a breaking change for scripts that make Zig releases -- I will
submit another PR to zig-bootstrap and release-cutter after this is
merged.
Using `FILE_DELETE_ON_CLOSE` can silently succeed without reporting any error
on non-empty directory. This commit adds usage of NtSetInformationFile
which will report `DIRECTORY_NOT_EMPTY`.
The CI now runs C backend tests in addition to compiling them. It uses
-std=c99 -pedantic -Werror in order to catch non-conformant C code.
This necessitated disabling a test case that caused a C compile error,
in addition to disabling a handful of warnings that are already being
triggered by Zig's C backend output for the behavior tests.
The upshot is that I was able to, very cleanly, integrate the C backend
tests into the build system, so that it communicates via the test runner
protocol along with all the other behavior tests.
Make the test targets use options that match the actual options of
CompileStep. This makes the code more straightforward, and ends up
making fewer tests incorrectly skipped. For example, now the CI runner
on Windows will no longer skip self-hosted x86_64 backend tests.

The commit correctly removed dest_builder from InstallArtifactStep, but
the change to installLibraryHeaders was incorrect since it affected
different steps than that one.
`GetPhysicallyInstalledSystemMemory` uses SMBios to grab the physical
memory size which can lead to unecessary allocation and inacurate
representation of the total memory. Using `System_Basic_Information`
help to retrieve the physical memory which is not reserved for the
kernel/tables. This aligns better with the linux side as `/proc/meminfo`
does the same thing.
