rs6000: Add tests for SSE4.1 "blend" intrinsics
Copy the tests for _mm_blend_pd, _mm_blendv_pd, _mm_blend_ps,
_mm_blendv_ps from gcc/testsuite/gcc.target/i386.

gcc/testsuite
* gcc.target/powerpc/sse4_1-blendpd.c: Copy from gcc.target/i386
and adjust dg directives to suit.
* gcc.target/powerpc/sse4_1-blendps-2.c: Likewise.
* gcc.target/powerpc/sse4_1-blendps.c: Likewise.
* gcc.target/powerpc/sse4_1-blendvpd.c: Likewise.
