BytecodeGenerator previously assumed that any UNALLOCATED variable must be a global object property, but that's incorrect for global lexical variables declared in a different script. This patch fixes the behavior by always falling back to the runtime to deal with deleting UNALLOCATED variables. This is sub-optimal, but should be correct, and it's unclear if speed is important for this case.
