Fixes a crash because we used a return-location for a deallocation instruction.

607318e0c7 Utility for correcting the nesting of stack allocation/deallocation instructions in SIL. 
This is useful for optimizations (like AllocBoxToStack) which create (de-)alloc_stack instructions.
They can just insert the new instructions anywhere without worrying about nesting and correct the nesting afterwards.
