Unwinds the destructor stack and creates destructors for each node between destructor_start_point and destructor_end_point (including the start, excluding the end).
If end_index
isn't passed, it will unwind the whole stack. If start_index
isn't passed, it will unwind from the current node.
When destructors are non-trivial (i.e. if they contain DECL or GOTO statements) then unwinding becomes more complicated because when we call convert on the destructor code it may recursively invoke this function.
Say we have a tree of [3, 2, 1, 0] and we start unwinding from top to bottom. If node 1 has such a non-trivial destructor during the convert it will add nodes to the tree so it ends up looking like this:
3, 2, 1, 0 5, 4,/
If for example the destructor contained a THROW statement then it would unwind destroying variables 5, 4 and finally 0. Note that we don't have 1 here even if that was the instruction that triggered the recursive unwind because it's already been popped off before convert is called.
After our unwind has finished, we return to our [3, 2, 1, 0] branch and continue processing the branch for destructor 0.
