shifting vectors of bytes as x86 doesn't have direct support for that. This removes a bunch of redundant masking in the generated code for SSE2 and SSE3. In order to avoid the really significant code size growth this would have triggered, I also factored the completely repeatative logic for shifting and masking into two lambdas which in turn makes all of this much easier to read IMO. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@238637 91177308-0d34-0410-b5e6-96231b3b80d8
