Note that this may be an incompatible ABI change -- we need to be
careful about the ABI issues surrounding this change and verify that
what we're doing is valid.
I think it's fine. Whether promotion is done on things that are neither
arguments not return values is transparent to the ABI and the design of
the mechanism was done to make that be true.
