rs6000: Add Power10 optimization for _mm_blendv*
Power10 ISA added `xxblendv*` instructions which are realized in the
`vec_blendv` instrinsic.
Use `vec_blendv` for `_mm_blendv_epi8`, `_mm_blendv_ps`, and
`_mm_blendv_pd` compatibility intrinsics, when `_ARCH_PWR10`.
Update original implementation of _mm_blendv_epi8 to use signed types,
to better match the function parameters. Realization is unchanged.
Also, copy a test from i386 for testing `_mm_blendv_ps`.
This should have come with commit ed04cf6d73e233c74c4e55c27f1cbd89ae4710e8,
but was inadvertently omitted.

* config/rs6000/smmintrin.h (_mm_blendv_epi8): Use vec_blendv
when _ARCH_PWR10. Use signed types.
(_mm_blendv_ps): Use vec_blendv when _ARCH_PWR10.
(_mm_blendv_pd): Likewise.

* gcc.target/powerpc/sse4_1-blendvps.c: Copy from gcc.target/i386,
adjust dg directives to suit.
