[ARM|RT] Merging r24766 into 3.9.1

Fixes a bug encountered in RC2 validation.

7331. By rengolin on 2016-11-19

[3.9.1] Merging r287359:

builtins: repair the builtins build with clang 3.8

When the C unwinding personality was corrected to match the ARM EHABI
specification, the unwind header in clang was updated with necessary
declarations. However, when building with an older compiler, we would not have
the necessary declarations. This would result in a build failure. Provide a
supplementary header to ensure that the necessary declarations are present for
the build of the C unwinding personality.

Note that this is NOT an ABI break. It merely is a compile time failure due to
the constants not being present. The constants here are reproduced
equivalently. This header should permit building with clang[<3.9] as well as
gcc.

Addresses PR31035!

[CMake] If the compiler supports _Atomic include atomic.c in builtins libraries

This fixes a long-standing TODO by implementing a compiler check for supporting the _Atomic keyword. If the _Atomic keyword is supported by the compiler we should include it in the builtin library sources.

Remove test/asan/TestCases/Darwin/dead-strip.c

The test is gated on OS version, but actually depends on what SDK
is used, see PR28743. Deleting to unblock 3.9.

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).
