Simon Pilgrim 89d9ff8229 [X86][SSE] foldShuffleOfHorizOp - add SHUFPS v4f32 handling ...

Fold shufps(hop(x,y),hop(z,w)) -> permute(hop(x,z)) - this is very similar to the equivalent unpack fold.

I did start trying to convert foldShuffleOfHorizOp to handle generic shuffle masks but we're relying on a lot of special cases at the moment.
