Return address save/restore logic is broken

Return address gets overwritten
Redesign the mechanism:
Treat $ra as a caller saved register. Caller saves it when making a call, restores it when the callee returns. Thus $ra will hold the return address while a function is running.
This way we won't need to save it at every label (thus get rid of the dirty hack) and don't need to restore at return statements.
