This revision now requires changes to proceed.

Why is this doing something different from the x86_64 implementation? We'd like to be able to, in the future, define different semantics from a tail exit, which means we need to distinguish the kind of exit is happening (tail call is just one, another is for exceptions, etc.) and this makes the arm implementation semantically different.
