- fixed: Resolving non-constant DECORATE expressions must be delayed until everything has been parsed.

If done as before, forward-declared classes cannot be found, and the immediate resolving is only needed for constant expressions, so explicitly enabling it in the 4 places where it is needed ensures that those unresolvable expressions remain intact until the final processing pass righr before the code generator is started.
