Subject: Move old movl vector_shuffle patterns. Not needed anymore since vector_shuffles shoul... 
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=233a64846ed00c3f120f75de8171b120f5009d33;p=oota-llvm.git

Move old movl vector_shuffle patterns. Not needed anymore since vector_shuffles shouldn't reach isel.
