[AVX-512] If gather mask is all ones, force the input to a zero vector. We were already forcing undef inputs to become a zero vector, this now catches an all ones mask too. Ideally we'd use undef and let execution dep fix handle picking the best register/clearance for the undef, but I don't think it can handle the early clobber today. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@297651 91177308-0d34-0410-b5e6-96231b3b80d8
