Not worth the absolutely miniscule performance difference, I think, since they turn a GPU emulation error into an emulator crash.

I think this should be OK for 1.15.3 ... Hm.

I think I tested these cases and the PSP GE just ignores a RET with an empty stack or a CALL with a full one. Been a bit, though.
