Simon Pilgrim 7f6cee9626 [X86][SSE] Improvements to byte shift shuffle matching 
Since (v)pslldq / (v)psrldq instructions resolve to a single input argument it is useful to match it much earlier than we currently do - this prevents more complicated shuffles (notably insertion into a zero vector) matching before it.
