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: Bug:16880454 Bug:16513433 Change-Id: I9b61e42307f96a114dce7552b6ead4ad1c544eab (cherry picked from commit 32429606bf696d3b2ca555f132a0d60c566d0bd0)
