Make stdatomic.h work with gcc4.6 host compiler
This is needed to make L work correctly, and bionic tests pass
again, after applying the equivalent of
commit 00aaea364501b3b0abe58dae461136159df1e356 there.
It makes the preexisting code that uses __sync implementations
much more useful, although we should no longer be exercising that
code in AOSP.
Specifically fixes:
We were invoking __has_extension and __has_builtin for GCC compilations.
They're clang specific. Restructured the tests.
The __sync implementation was not defining the LOCK_FREE macros.
ATOMIC_VAR_INIT was using named field initializations. These are a
C, not C++, feature, that is not supported by g++ 4.6.
The stdatomic bionic test still failed with 4.6 and glibc with our
questionable LOCK_FREE macro implementation. Don't run that piece
with 4.6.
In L, this is a prerequisite for fixing:

Fix, generalize stdatomic.h; improve test.
We seem to use this stdatomic.h sometimes, and slightly different prebuilts
at other times, making them all difficult to test, and making it unclear
which one we're testing. This generalizes the bionic header so that it
can be used directly as the prebuilt header as well. So long as they
don't diverge again, that should somewhat improve test coverage.
Use the correct builtin for atomic_is_lock_free.
Fix atomic_flag_init.
Turn on atomic tests even with __GLIBC__, since they now appear to pass.
Include uchar.h in stdatomic.h where needed.
Add a basic memory ordering test.
Fix bit-rotted comments in bionic tests makefile.
Prerequisite for fixing b/16880454 and

[MIPS] Fix atomic_is_lock_free test for mips32.
On 32-bit MIPS, 64-bit atomic ops are achieved through locks.
So allow the test to fail for atomic_intmax_t on 32-bit MIPS.

Fixes stdatomic.h test to match C11 spec
C11 defines the expected value to atomic_compare_exchange_* as being non-atomic
types. Using an atomic type is a syntax error in clang.
