libc++: test lock-free atomic alignment
Summary:
libc++ implements std::atomic<_Tp> using __atomic_base<_Tp> with
`mutable _Atomic(_Tp) __a_`. That member must be suitably aligned on
relevant ISAs for instructions such as cmpxchg to work properly, but
this alignment isn't checked anywhere. __atomic_base's implementation
relies on _Atomic doing "the right thing" since it's under the
compiler's control, and only the compiler knows about lock-freedom and
instruction generation. This test makes sure that the compiler isn't
breaking libc++'s expectations.
I'm looking at a few odd things in the C++ standard, and will have a few
other fixes around this area in the future.
This requires building with `-DLIBCXX_HAS_ATOMIC_LIB=True`, the test
marks the dependency as REQUIRES and won't be run without.

[CFLAA] Remove modref queries from CFLAA.
As it turns out, modref queries are broken with CFLAA. Specifically,
the data source we were using for determining modref behaviors

note e.g. storing an i32 to an i32* (or loading an i64 from an i64*).
It also ignores external function calls, rather than acting
conservatively for them.
(N.B. These operations, where necessary, *are* tracked by CFLAA; we just
use a different mechanism to do so. Said mechanism is relatively

Add more gcc compatibility names to clang's cpuid.h
Summary:
Some cpuid bit defines are named slightly different from how gcc's
cpuid.h calls them.
Define a few more compatibility names to appease software built for gcc:
* `bit_PCLMUL` alias of `bit_PCLMULQDQ`
* `bit_SSE4_1` alias of `bit_SSE41`
* `bit_SSE4_2` alias of `bit_SSE42`
* `bit_AES` alias of `bit_AESNI`
* `bit_CMPXCHG8B` alias of `bit_CX8`
While here, add the misssing 29th bit, `bit_F16C` (which is how gcc
calls this bit).

XFAIL one sanitizer symbolizer test for FreeBSD
Summary:
Due to a QoI issuse in FreeBSD's libcxxrt-based demangler, one sanitizer
symbolizer test consistently appears to fail:
Value of: DemangleSwiftAndCXX("foo")
Actual: "float"
Expected: "foo"
This is because libcxxrt's __cxa_demangle() incorrectly demangles the "foo"
identifier to "float". It should return an error instead.
For now, XFAIL this particular test for FreeBSD, until we can fix libcxxrt
properly (which might take some time to coordinate with upstream).
