[x86] fix remaining miscompile bug in horizontal binop matching (PR40243) When we use the partial-matching function on a 128-bit chunk, we must account for the possibility that we've matched undef halves of the original source vectors, so the outputs may need to be reset. This should allow closing PR40243: https://bugs.llvm.org/show_bug.cgi?id=40243 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@350830 91177308-0d34-0410-b5e6-96231b3b80d8
