[X86] Add test case that shows failure to use a vector ANDN when both inputs to the AND are XORs. The matching code tries to canonicalize XOR to the left, but if there are two XORs and only one is a vnot, this canonicalization can prevent matching. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@293402 91177308-0d34-0410-b5e6-96231b3b80d8
