reflect: promote integer closure return to full word

The libffi library expects an integer return type to be promoted to a
full word.  Implement that when returning from a closure written in Go.
This only matters on big-endian systems when returning an integer smaller
than the pointer size, which is why we didn't notice it until now.

Fixes https://gcc.gnu.org/PR91781.
