Use __builtin_tgmath in tgmath.h with GCC 8 (bug 21660).
GCC mainline now supports __builtin_tgmath to allow <tgmath.h> macro implementations that expand their arguments only once, so avoiding exponential blowup in the size of macro expansions when calls to those macros are nested in arguments to those macros. This patch makes glibc's tgmath.h support using __builtin_tgmath, as a much simpler and more efficient alternative to the existing implementation. (As a side effect, the new feature would make it much more practical to support decimal floating point in <tgmath.h> with new compilers; currently, libdfp does not provide a <tgmath.h> implementation, and making decimal arguments cause integer arguments to be considered of type _Decimal64 instead of double would have been very problematic in the old implementation.) Tested for x86_64 (with GCC mainline). [BZ #21660] * math/tgmath.h (__HAVE_BUILTIN_TGMATH): New macro. [__HAVE_BUILTIN_TGMATH] (__TG_F16_ARG): Likewise.
