[PATCH] D51203: AMDGPU: Handle 32-bit address wraparounds for SMRD opcodes

[Marek Olšák via Phabricator via llvm-commits]

We can ignore old Mesa + new LLVM, because LLVM 7 is the first release to have 32-bit pointers, and I think we can fix that before release.

For internal driver additions, e.g. offset + small constant, the driver can use NUW or NSW. For app additions, we would just use normal Add. As long as NUW or NSW is preserved, we should be fine.
