Currently, SANITIZER_COMMON_SUPPORTED_OS is being used to enable many libraries.
Unfortunately this makes it impossible to selectively disable a library based on the OS.
This patch removes this limitation by adding a separate list of supported OSs for the lsan, ubsan, ubsan_minimal, and stats libraries.

D98452 introduced a mismatch between clang expectations for

adding a case for baremetal. This now matches the output of

There's a lot of duplicated calls to find various compiler-rt libraries
from build of runtime libraries like libunwind, libc++, libc++abi and
compiler-rt. The compiler-rt helper module already implemented caching
for results avoid repeated Clang invocations.
This change moves the compiler-rt implementation into a shared location
and reuses it from other runtimes to reduce duplication and speed up
the build.

Enable building the ORC runtime for 64-bit and 32-bit ARM architectures,
and for all Darwin embedded platforms (iOS, tvOS, and watchOS). This
covers building the cross-platform code, but does not add TLV runtime
support for the new architectures, which can be added independently.
Incidentally, stop building the Mach-O TLS support file unnecessarily on
other platforms.

rG210d72e9d6b4a8e7633921d0bd7186fd3c7a2c8c moved the check from
builtin-config-ix to config-ix so that the check would be made even when
the builtins are not built. However, now the check is no longer made
when the builtins are built standalone which causes the builtins to fail
to build.
Add the check back to builtins-config-ix so that the check gets
performed both when the builtins are not built, and when they are built
standalone.

Previously we used the minimum deployment target used for the platform
(e.g. iOS is 9.0). Unfortunately this leads to ABI incompatibilities with
arm64e devices running newer OSs. In particular the following TSan test
cases that used libcxx would fail due to the ABI mismatch.
* Darwin/libcxx-shared-ptr-recursive.mm
* Darwin/libcxx-shared-ptr-stress.mm
* Darwin/libcxx-shared-ptr.mm
* libcxx/std_shared_ptr.cpp
Given that arm64e is not ABI stable we should ideally match the
deployment target for sanitizer runtimes and their tests cases to the
device when building for arm64e. Unfortunately having a mixed deployment
target (based on architecture) isn't currently supported by the build system
and is non-trivial to implement.
As a stop-gap measure this patch changes the sanitizer test suites (but not the
sanitizer runtimes themselves) to use a newer deployment target when
targetting arm64e.
The deployment target used for arm64e is the SDK version because this
"should" match the OS version running on the target device (it is a
configuration error to not match them).

9ee64c3746 has started using
COMPILER_RT_HAS_OMIT_FRAME_POINTER_FLAG inside scudo. However,
the relevant CMake check was performed in builtin-config-ix.cmake,
so the definition was missing when builtins were not built. Move
the check to config-ix.cmake, so that it runs unconditionally of
the components being built.

This updates llvm/utils/sysroot.py to include the "DIA SDK" folder in the
sysroot.
It also updates the build to look for the DIA SDK there if a sysroot is set.
This requires moving LLVM_WINSYSROOT to config-ix.cmake.
For the GN build, I chose to pass a qualified path to diaguids in libs instead
of pushing a config with a `/libpath:` flag. The former requires a GN with
https://gn-review.googlesource.com/c/gn/+/12200, the latter requires D109624.
The former is more like the cmake build, arguably a bit simpler, and it's
easier to check for the wrong GN revision and easier to update GN.

The __attribute__((format)) was added somewhere in 2012,
the lost during refactoring, then re-added in 2014 but
to te source files, which is a no-op.
Move it back to header files so that it actually takes effect.
But over the past 7 years we've accumulated whole lot of
format string bugs of different types, so disable the warning
with -Wno-format for now for incremental clean up.
Among the bugs that it warns about are all kinds of bad things:
- wrong sizes of arguments
- missing/excessive arguments
- printing wrong things (e.g. *ptr instead of ptr)
- completely messed up format strings
- security issues where external string is used as format
