Chandler Carruth c5114dbcc3 [x86] Teach the target combine step to aggressively fold pshufd insturcions. 
Summary:
This allows it to fold pshufd instructions across intervening
half-shuffles and other noise. This pattern actually shows up in the
generic lowering tests, but I've also added direct tests using
intrinsics to make sure that the specific desired functionality is
working even if the lowering stuff changes in the future.
