New Revision: 146344

URL: http://llvm.org/viewvc/llvm-project?rev=146344&view=rev
Log:
Remove some remants of the old palign pattern fragment that were still hanging around. Also remove a cast from inside getShuffleVPERM2X128Immediate and getShuffleVPERMILPImmediate since the only caller already had done the cast.
