Possibly, but it's a slightly different matter which I should probably deal with in another PR, wherein we handle the fact that the Program AS needn't be 0. AFAICT these intrinsics are here to support GCC's `__builtin_eh_return`, and the pointer arg is supposed to point to a handler function in the Program AS. I think it's preferable to handle that topic independently since it'll spawn its own lively discussion, no doubt.
