Fix a crash when transmuting non-immediate to immediate types
The code to build the transmute intrinsic currently makes the invalid assumption that if the in-type is non-immediate, the out-type is non-immediate as well. But this is wrong, for example when transmuting [int, ..1] to int. So we need to handle this fourth case as well. Fixes #7988
