This testcase was originally part of r284995, but I put it in a wrong directory. So I removed it. Before adding it back I did some small enhancements. Also I changed the assertions a little bit, to take into account the impact of some changes performed since code review is done. This is similar to changes done for another testcase in the original commit. See: https://reviews.llvm.org/D23614#577749 Basically for instead of vxor we now generate xxlxor in some cases, which is better. llvm-svn: 285333
