  - `a = x; a = a || y;`
- terminate upon `debugger;`

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.

fixes #1787

fix chained evaluation (#1610 )

`reduce_vars` enables substitution of variables but did not clone the value's `AST_Node`.

This confuses `collapse_vars` and result in invalid AST and subsequent crash.

fixes #1609
