New Revision: 147345

URL: http://llvm.org/viewvc/llvm-project?rev=147345&view=rev
Log:
Mark non-VEX forms of PCLMUL instructions as requiring SSE2 to be enabled along with CLMUL. That's required for the XMM registers to be valid for integer data. Doesn't change any behavior since the CLMUL instructions don't have patterns yet.
