Hi,

This patch implements missing intrinsics:
_mm256_set_m128
_mm256_set_m128d
_mm256_set_m128i
_mm256_setr_m128
_mm256_setr_m128d
_mm256_setr_m128i

gcc/
        * config/i386/avxintrin.h (_mm256_set_m128, _mm256_set_m128d,
        _mm256_set_m128i, _mm256_setr_m128, _mm256_setr_m128d,
        _mm256_setr_m128i): New intrinsics.

gcc/testsuite/
        * gcc.target/i386/avx-vinsertf128-256-1: Test new intrinsics.
        * gcc.target/i386/avx-vinsertf128-256-2: Ditto.

Ok for trunk?
