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.

fix hoist_vars on reduce_vars ( #1607 )

`hoist_vars` converts variable declarations into plain assignments, which then confuses `reduce_vars`

fix stack issues with AST_Node.evaluate() ( #1603 )
...
As patched in #1597 , `make_node_from_constant()` makes inconsistent and sometimes incorrect calls to `optimize()` and `transform()`.
Fix those issues properly by changing the semantics of `evaluate()` and `make_node_from_constant()`, with the side effect that `evaluate()` no longer eagerly converts constant to `AST_Node`.

fix AST_Node.optimize() ( #1602 )
...
Liberal use of `Compressor.transform()` and `AST_Node.optimize()` presents an issue for look-up operations like `TreeWalker.in_boolean_context()` and `TreeWalker.parent()`.
This is an incremental fix such that `AST_Node.optimize()` would now contain the correct stack information when called correctly.

disallow parameter substitution for named IIFEs ( #1596 )
