Sam Blackshear 30a7a2fd8e Fixing Symexec_memory error that occurs when dereferencing the return value of an undefined function ... Summary: @​public Infer previously did not work correctly when a function returns the result of a skip function: ``` retUndef() { x = undefined(); return x; } derefUndef() { y = retUndef(); y.doSomething(); // Symexec_memory_error here, prevents spec inference } ``` The problem is that angelic mode did not know to add the return value of `retUndef()` to the footprint. This diff fixes the problem by adding return values marked with the `Aundef` attribute to the footprint. This is done lazily (e.g., a value only gets added to the footprint when you try to deref it).
