We can vectorize them because in the case where we wrap in the address space the unvectorized code would have had to access a pointer value of zero which is undefined behavior in address space zero according to the LLVM IR semantics. (Thank you Duncan, for pointing this out to me). Fixes PR16592. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186088 91177308-0d34-0410-b5e6-96231b3b80d8
