Details

Having an exit block is a step towards inlining. When you have a definitive exit block it's easier to graft an inlined-call-target CFG into the calling block.
When the target CFG gets grafted into the caller, you inspect the control instruction predecessors of the exit block to transform MReturn instructions into MGotos.
To small to have its own bug/patch -- we just cons up the exit points in the builder.
