Craig Topper 76bc3d6e07 [X86] In lowerVectorShuffle, instead of creating a new node to canonicalize the shuffle mask by commuting, just commute the mask and swap V1/V2. 
LegalizeDAG tries to legal the DAG by legalizing nodes before
their operands.

If we create a new node, we end up legalizing it after its operands.
This prevents some of the optimizations that can be done when the
operand is a build_vector since the build_vector will have been
legalized to something else.
