[Mingw-w64-public] intrin-impl.h compile warning: this use of "defined" may not be portable

Hello, gcc 8.3 for file mingw-w64-headers/include/psdk_inc/intrin-impl.h throws 300 lines of preprocessor warnings: "defined" may not be portable. It can be reproduced just by calling cpp on that file with parameters: -D__MINGW_INTRIN_INLINE -Wall -Wextra $ i686-w64-mingw32-cpp mingw-w64-headers

GCC 6.0 has introduced a new feature that allows inline asm to return flag registers (see https://gcc.gnu.org/onlinedocs/gcc/Extended-Asm.html#FlagOutputOperands). There are a couple dozen intrinsics in intrin-impl.h that would benefit from using this. There is a define that signals if the gc
