creation to a function and use that function for both Darwin and

Summary:
The Quarantine is used to hold chunks for a little while prior to
actually releasing them for potential reuse. The code is pretty much
the same as the sanitizer_common one, with additional shuffling of
the quarantine batches to decrease predictability of allocation
patterns when it is enabled.

The tests fork.text, fork.sigusr.test and fork-ubsan.test intermittently
fail on the aarch64 buildbots. Input gathered from the fork.sigusr.test
implies that when the builder is under load the timeout value is not
sufficient. The fork-ubsan.test doesn't have a timeout and I think is not
always finding the error after 10000 runs so I've marked it as unsupported
for now.

Summary: When libc++ is used to build CLANG, its XRay libraries libclang_rt.xray-*.a have dependencies on libc++. Therefore, libc++ is needed to link and run XRay test cases. For Linux -rpath is also needed to specify where to load libc++. This change sets macro LLVM_LIBCXX_USED to 1 if libc++ is actually used in the build. XRay tests then check the flag and add -L<llvm_shlib_dir> -lc++ and -Wl,-rpath=<llvm_shlib_dir> if needed.

Currently VMO in Zircon create using the zx_vmo_create is resizable
by default, but we'll be changing this in the future, requiring an
explicit flag to make the VMO resizable.
Prepare for this change by passing ZX_VMO_RESIZABLE option to all
zx_vmo_create calls that need resizable VMO.

This follows up after b7692bc3e9 "[UBSan] Fix
isDerivedFromAtOffset on iOS ARM64" fixed the RTTI comparison in
isDerivedFromAtOffset on just one platform and then
a25a2c7c9a "Always compare C++ typeinfo (based on
libstdc++ implementation)" extended that fix to more platforms.
But there is another RTTI comparison for -fsanitize=function generated in
clang's CodeGenFunction::EmitCall as just a pointer comparison. For
SANITIZER_NON_UNIQUE_TYPEINFO platforms this needs to be extended to also do
string comparison. For that, __ubsan_handle_function_type_mismatch[_abort]
takes the two std::type_info pointers as additional parameters now, checks them
internally for potential equivalence, and returns without reporting failure if
they turn out to be equivalent after all. (NORETURN needed to be dropped from
the _abort variant for that.) Also these functions depend on ABI-specific RTTI
now, so needed to be moved from plain UBSAN_SOURCES (ubsan_handlers.h/cc) to
UBSAN_CXXABI_SOURCES (ubsan_handlers_cxx.h/cc), but as -fsanitize=function is
only supported in C++ mode that's not a problem.

On Linux both version of the INTERCEPT_FUNCTION macro now return true
when interception was successful. Adapt and cleanup some usages.
Also note that `&(func) == &WRAP(func)` is a link-time property, but we
do a runtime check.
Tested on Linux and macOS.
Previous attempt reverted by: 5642c3feb0
This attempt to bring order to the interceptor macro goes the other
direction and aligns the Linux implementation with the way things are
done on Windows.

The fork-siguser.test and fork.test intermittently fail on the AArch64
buildbot. Unfortunately these failures are not reproducible on a similar
machine and seem to fail when the machines are under load. Before
suggesting the tests be marked unsupported for AArch64 we'd like to see
if we can get some more information about the failures to see if it helps
us reproduce. This patch adds --dump-input-on-failure to the FileCheck
commands to see if we can get some more information about the failures.

Changing INTERCEPT_FUNCTION to return void is not functionally correct.
IMO the best way to communicate failure or success of interception is
with a return value, not some external address comparison.
This change was also creating link errors for _except_handler4_common,
which is exported from ucrtbase.dll in 32-bit Windows.
Also revert dependent changes r359362 and r359466.

compatibility with system's toolchain
This patch aims to:
- Guard ompiler-rt/test/builtins/Unit/compiler_rt_logb_test.c with macros, so
the test runs on GLIBC versions >= 2.23. This is because the test relies on
comparing its computed values to libm. Oolder versions might not compute to the
same value as the compiler-rt value.
- Update compiler-rt/test/sanitizer_common/TestCases/Posix/getpw_getgr.cc
so that std::string is not used, since false positives may be detected.

Summary:
This CL implements the memory reclaiming function `releaseFreeMemoryToOS`
and its associated classes. Most of this code was originally written by
Aleksey for the Primary64 in sanitizer_common, and I made some changes to
be able to implement 32-bit reclaiming as well. The code has be restructured
a bit to accomodate for freelist of batches instead of the freearray used
in the current sanitizer_common code.
