  Log Message:
  -----------
  [X86] Move ENCODEKEY128/256 handling from lowering to selection.

We should avoid emitting MachineSDNodes from lowering.

We can use the the implicit def handling in InstrEmitter to avoid
manually copying from each xmm result register. We only need to
manually emit the copies for the implicit uses.
