Sanjay Patel 81b61c0e50 [X86, SSE] instcombine common cases of insertps intrinsics into shuffles 
This is very similar to D8486 / r232852 (vperm2). If we treat insertps intrinsics
as shufflevectors, we can optimize them better.

I've left all but the full zero case of the zero mask variants out of this patch. 
I don't think those can be converted into a single shuffle in all cases, but I'd
be happy to be proven wrong as I was for vperm2f128.

Either way, we'd need to support whatever sequence we come up with for those cases
in the backend before converting them here.

Please see the documentation provided in docs/ for further
assistance with LLVM, and in particular docs/GettingStarted.rst for getting
started with LLVM and docs/README.txt for an overview of LLVM's
