  -----------
  [libcxx][test] Use TEST_HAS_BUILTIN in test code

... rather than using `__has_builtin` directly. This both (1) allows a compiler that doesn't speak `__has_builtin` to workaround with preprocessor magic, and (2) avoids diagnostics about things that look like function like macros after `#if` but are not.
