actual support for complex AVX shuffling tricks. We can do independent blends of the low and high 128-bit lanes of an avx vector, so shuffle the inputs into place and then do the blend at 256 bits. This will in many cases remove one blend instruction. The next step is to permute the low and high halves in-place rather than extracting them and re-inserting them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@218202 91177308-0d34-0410-b5e6-96231b3b80d8
