New Revision: 113985

URL: http://llvm.org/viewvc/llvm-project?rev=113985&view=rev
Log:
Recognize VST1q64Pseudo and VSTMQ as stack slot stores.
Recognize VLD1q64Pseudo as a stack slot load.

Reject these if they are loading or storing a subregister. The API (and
VirtRegRewriter) doesn't know how to deal with that.
