default ExitSlot createExitSlot(long target, RegisterValue ctx) {

	}
Construct an exit slot for the given branch target

<p>
This is invoked by generated constructors for each branch target that exits the passage. Each
is saved as a field and will be filled lazily with its chained entry point the first time the
branch is taken.

@param target the target program counter
@param ctx the target decode context
@return the exit slot
