v4:
- Of original 6 patches in this series, I committed patches 2-5.
- Found an issue from v3. New file "nmmintrin.h" also needs to be added
to gcc/config.gcc "extra_headers". Unfortunately, I discovered this
after committing the patch which added "nmmintrin.h", so I've added a
new patch here.
- Added scheduling "barriers" to patch 2 after review from Segher.
- Noted additional PR fixed by patch 3.
v3: Add "nmmintrin.h". _mm_cmpgt_epi64 is part of SSE4.2
and users will expect to be able to include "nmmintrin.h",
even though "nmmintrin.h" just includes "smmintrin.h"
where all of the SSE4.2 implementations actually appear.
Only patch 5/6 changed from v2.
Tested ppc64le (POWER9) and ppc64/32 (POWER7).
OK for trunk?

rs6000: Add nmmintrin.h to extra_headers
rs6000: Support SSE4.1 "round" intrinsics

Suppress exceptions (when specified), by saving, manipulating, and
restoring the FPSCR. Similarly, save, set, and restore the floating-point
rounding mode when required.
No attempt is made to optimize writing the FPSCR (by checking if the new
value would be the same), other than using lighter weight instructions
when possible. Note that explicit instruction scheduling "barriers" are
added to prevent floating-point computations from being moved before or
after the explicit FPSCR manipulations. (That these are required has
been reported as an issue in GCC: PR102783.)
The scalar versions naively use the parallel versions to compute the
single scalar result and then construct the remainder of the result.
Of minor note, the values of _MM_FROUND_TO_NEG_INF and _MM_FROUND_TO_ZERO
are swapped from the corresponding values on x86 so as to match the
corresponding rounding mode values in the Power ISA.
Move implementations of _mm_ceil* and _mm_floor* into _mm_round*, and
convert _mm_ceil* and _mm_floor* into macros. This matches the current
analogous implementations in config/i386/smmintrin.h.
Function signatures match the analogous functions in config/i386/smmintrin.h.
Add tests for _mm_round_pd, _mm_round_ps, _mm_round_sd, _mm_round_ss,
modeled after the very similar "floor" and "ceil" tests.
Include basic tests, plus tests at the boundaries for floating-point
representation, positive and negative, test all of the parameterized
rounding modes as well as the C99 rounding modes and interactions
between the two.
Exceptions are not explicitly tested.

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.

I assume this improves on all previous commented things (you don't say
if it does).

* Re: [PATCH v4 2/3] rs6000: Support SSE4.1 "round" intrinsics

Suppress exceptions (when specified), by saving, manipulating, and
restoring the FPSCR. Similarly, save, set, and restore the floating-point
rounding mode when required.
No attempt is made to optimize writing the FPSCR (by checking if the new
value would be the same), other than using lighter weight instructions
when possible. Note that explicit instruction scheduling "barriers" are
added to prevent floating-point computations from being moved before or
after the explicit FPSCR manipulations. (That these are required has
been reported as an issue in GCC: PR102783.)
The scalar versions naively use the parallel versions to compute the
single scalar result and then construct the remainder of the result.
Of minor note, the values of _MM_FROUND_TO_NEG_INF and _MM_FROUND_TO_ZERO
are swapped from the corresponding values on x86 so as to match the
corresponding rounding mode values in the Power ISA.
Move implementations of _mm_ceil* and _mm_floor* into _mm_round*, and
convert _mm_ceil* and _mm_floor* into macros. This matches the current
analogous implementations in config/i386/smmintrin.h.
Function signatures match the analogous functions in config/i386/smmintrin.h.
Add tests for _mm_round_pd, _mm_round_ps, _mm_round_sd, _mm_round_ss,
modeled after the very similar "floor" and "ceil" tests.
Include basic tests, plus tests at the boundaries for floating-point
representation, positive and negative, test all of the parameterized
rounding modes as well as the C99 rounding modes and interactions
between the two.
Exceptions are not explicitly tested.
