Alex Lam S.L ff289b90a9 implement delayed resolution for reduce_vars (#1788)
Although it would be nice to enforce `AST_Node` cloning during transformation, that ship has sailed a long time ago.

We now get the assigned value when resolving `AST_SymbolRef` instead of `reset_opt_flags()`, which has the added advantage of improved compressor efficiency.
