[PATCH] D37399: [X86][TableGen] Teach tblgen to allow SDNPCommutable nodes with more than 2 operands. Use it to remove and enhance FMA patterns

The patch looks good.
But IMHO it should be split into one NFC patch with the TableGen changes, and another for updating the nodes accordingly and removing the unneeded patterns.
