[X86] Add test cases for opportunities to use KTEST when check if the result of ANDing two mask registers is zero. The test cases are constructed to avoid folding the AND into a masked compare operation. Currently we emit a KAND and a KORTEST for these cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@350287 91177308-0d34-0410-b5e6-96231b3b80d8
