... and extend JS node wrapper functionality.

Node wrappers now have accessors for value inputs and
context/control/effect/frame-state inputs. Accessors are typed,
although types aren't very meaningful so far (in current examples we
only distinguish between Object/HeapObject).

The following node kinds now take an additional feedback vector input,
and use the new node wrapper functionality above:

- CloneObject
- CreateLiteralArray
- CreateLiteralObject
- CreateLiteralRegExp
- GetIterator
- GetTemplateObject
- HasProperty
- LoadProperty
- StoreProperty
