shuffle before inserting on a 256-bit vector. - Add AVX versions of movd/movq instructions - Introduce a few COPY patterns to match insert_subvector instructions. This turns a trivial insert_subvector instruction into a register copy, coalescing the xmm into a ymm and avoid emiting on more instruction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136002 91177308-0d34-0410-b5e6-96231b3b80d8
