Summary:
Executes both LTO and ThinLTO CFI tests an additional time using the new
pass manager. I only bothered to add with gold and not lld as testing
with one linker should be sufficient. I didn't add for APPLE or WIN32
since I don't have a way to test those.
Depends on D49429.

Summary:
Run CFI tests on all targets current toolchain can target.
On multiarch Linux, this will run all CFI tests with -m32 and -m64.

We now avoid using absolute symbols on Windows (D37407 and D37408),
so this should work.
Fixes PR32770.

These were added in r301016, but they're failing, because
-fsanitize=cfi seemingly causes -flto=thin to emit raw bitcode objects,
rather than the mach-o-wrapped bitcode we emit with -flto=thin alone.
That causes all tests to fail with ld64 errors.
Filed PR32741.

Summary:
This patch is a refactoring of the way cmake 'targets' are grouped.
It won't affect non-UI cmake-generators.
Clang/LLVM are using a structured way to group targets which ease
navigation through Visual Studio UI. The Compiler-RT projects
differ from the way Clang/LLVM are grouping targets.
This patch doesn't contain behavior changes.

This is part of a new statistics gathering feature for the sanitizers.

This is an initial version of the runtime cross-DSO CFI support
library.
It contains a number of FIXMEs, ex. it does not support the
diagnostic mode nor dlopen/dlclose, but it works and can be tested.
Diagnostic mode, in particular, would require some refactoring (we'd
like to gather all CFI hooks in the UBSan library into one function
so that we could easier pass the diagnostic information down to
__cfi_check). It will be implemented later.
Once the diagnostic mode is in, I plan to create a second test
configuration to run all existing tests in both modes. For now, this
patch includes only a few new cross-DSO tests.

Summary:
Rather than having to add new "experimental" options each time someone wants to work on bringing a sanitizer to a new platform, this patch makes options for all of them.
The default values for the options are set by the platform checks that would have enabled them, but they can be overridden on or off.

We will use this for ASan on Windows soon. When the ELF port of LLD
matures, we can add other sanitizer integration tests to make sure they
work with LLD.

Specifically:
- Start using %expect_crash.
- Provide an implementation of __ubsan::getDynamicTypeInfoFromVtable
for the Microsoft C++ ABI. This is all that is needed for CFI
diagnostics; UBSan's -fsanitize=vptr also requires an implementation of
__ubsan::checkDynamicType.
- Build the sanitizer runtimes against the release version of the C
runtime, even in debug builds.
- Accommodate demangling differences in tests.

This rule works like check-cfi, but fails if the tests are unsupported.
This is useful to run on bots if we want to be sure that the tests aren't
silently being skipped.
