Don't use runtime bounds check between address spaces.
Don't vectorize with a runtime check if it requires a comparison between pointers with different address spaces. The values can't be assumed to be directly comparable. Previously it would create an illegal bitcast. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191862 91177308-0d34-0410-b5e6-96231b3b80d8
