Subject: Replace EVT with MVT in isVectorShift. Keeps compiler from generating unneeded checks... 
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=d36b53e764b742c2ba16ae2b2517646694e05bff;p=oota-llvm.git

Replace EVT with MVT in isVectorShift. Keeps compiler from generating unneeded checks and handling for extended types.
