[X86] Remove and autoupgrade kand/kandn/kor/kxor/kxnor/knot intrinsics.
Clang already stopped using these a couple months ago. The test cases aren't great as there is nothing forcing the operations to stay in k-registers so some of them moved back to scalar ops due to the bitcasts being moved around. llvm-svn: 324177
