Yeah, definitely. For the standalone headers, which have currently
__<FEATURE>__ guards inside of it, please replace it by the larger snippets
involving #pragma, and in the x86intrin.h/immintrin.h headers include those
unconditionally, instead of just if __<FEATURE>__ is defined.
For the non-standalone headers (newer ones like avxintrin.h), replace
the #ifdef __<FEATURE>__ in immintrin.h/x86intrin.h with larger snippets.
