    rs6000: Fix up #include <immintrin.h> or <x86gprintrin.h> [PR104239]
    
    r12-4717-g7d37abedf58d66 added immintrin.h and x86gprintrin.h headers
    to rs6000, these headers are on x86 standalone headers that various
    programs include directly rather than including them through
    <x86intrin.h>.
    Unfortunately, for that change the bmiintrin.h and bmi2intrin.h
    headers haven't been adjusted, so the effect is that if one includes them
    (without including also x86intrin.h first) #error will trigger.
    Furthermore, when including such headers conditionally as some real-world
    packages do, this means a regression.
    
    The following patch fixes it and matches what the x86 bmi{,2}intrin.h
    headers do.

            * config/rs6000/bmiintrin.h: Test _X86GPRINTRIN_H_INCLUDED instead of
            _X86INTRIN_H_INCLUDED and adjust #error wording.
            * config/rs6000/bmi2intrin.h: Likewise.
    
            * gcc.target/powerpc/pr104239-1.c: New test.
