With the new world order, it can handle cases where the first store into the alloca is an element of the vector, instead of requiring the first analyzed store to have the vector type itself. This allows us to un-xfail test/CodeGen/X86/vec_ins_extract.ll. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63590 91177308-0d34-0410-b5e6-96231b3b80d8
