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. 2021-07-30 Paul A. Clarke <pc@us.ibm.com> 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.
