cc6aa3e5ac fix incorrect context in variable substitution (#1791) 
`AST_Node.optimize()` is context-aware, so don't cache its results to be used elsewhere.

Also fixed a few cases of AST corruption and beef up safety of `pure_getters`.

06cdb74279 improve pure_getters (#1786) 
- property access to `null` & `undefined` always has side effects
- utilise `reduce_vars` to determine safe property access
- may-be cases treated as side effects unless `unsafe`

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.

fixes #1787

- better heuristics to avoid issues like #1532
- fix `TreeWalker.loopcontrol_target()`
  - `continue` cannot refer to `switch` blocks
