Yeah.  You could have done that yourself :-)

The bug can always be reopened, if it turns out not to be fixed.

So this looks fixed and we can mark it RESOLVED / FIXED?

rs6000: Guard some x86 intrinsics implementations

Some compatibility implementations of x86 intrinsics include
Power intrinsics which require POWER8.  Guard them.

emmintrin.h:
- _mm_cmpord_pd: Remove code which was ostensibly for pre-POWER8,
  but which indeed depended on POWER8 (vec_cmpgt(v2du)/vcmpgtud).
  The "POWER8" version works fine on pre-POWER8.
- _mm_mul_epu32: vec_mule(v4su) uses vmuleuw.
pmmintrin.h:
- _mm_movehdup_ps: vec_mergeo(v4su) uses vmrgow.
- _mm_moveldup_ps: vec_mergee(v4su) uses vmrgew.
smmintrin.h:
- _mm_cmpeq_epi64: vec_cmpeq(v2di) uses vcmpequd.
- _mm_mul_epi32: vec_mule(v4si) uses vmuluwm.
- _mm_cmpgt_epi64: vec_cmpgt(v2di) uses vcmpgtsd.
tmmintrin.h:
- _mm_sign_epi8: vec_neg(v4si) uses vsububm.
- _mm_sign_epi16: vec_neg(v4si) uses vsubuhm.
- _mm_sign_epi32: vec_neg(v4si) uses vsubuwm.
  Note that the above three could actually be supported pre-POWER8,
  but current GCC does not support them before POWER8.
- _mm_sign_pi8: depends on _mm_sign_epi8.
- _mm_sign_pi16: depends on _mm_sign_epi16.
- _mm_sign_pi32: depends on _mm_sign_epi32.

sse4_2-pcmpgtq.c:
- _mm_cmpgt_epi64: vec_cmpeq(v2di) uses vcmpequd.

I'll take ownership of this, except I'm not sure how to effect that.

The fix has been posted
https://gcc.gnu.org/pipermail/gcc-patches/2021-August/577023.html, and awaits
reviews/approval.
