Hi!
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.
Bootstrapped/regtested on powerpc64le-linux, ok for trunk?

* config/rs6000/bmiintrin.h: Test _X86GPRINTRIN_H_INCLUDED instead of
_X86INTRIN_H_INCLUDED and adjust #error wording.
* config/rs6000/bmi2intrin.h: Likewise.
