This commit fixes an issue introduced as part of the fix for GHSA-5fhj-g3p3-pq9g. The `reftyped_vregs` list given to `regalloc2` is not allowed to have duplicates in it and while the list originally doesn't have duplicates once aliases are applied the list may have duplicates. The fix here is to perform another pass to remove duplicates after the aliases have been processed.
This carries over a narrow fix from bytecodealliance#4427 to prior release branches. The patch here was created by `@uweigand` during the investigation for bytecodealliance#4487.

This includes an s390x-specific fix for constants but an additional all-platforms fix for the reftyped_vregs array.
