Andrea Di Biagio bf0fb36d72 Revert r211771. It was: "[X86] Improve the selection of SSE3/AVX addsub instructions". 
This chang fully reverts r211771.
That revision added a canonicalization rule which has the potential to causes a
combine-cycle in the target-independent canonicalizing DAG combine.

The plan is to move the logic that forms target specific addsub nodes as part of
the lowering of shuffles.
