fix sign extension in casting enums
The function cast_value() needs the exact type of the old expression
but when called via cast_enum_list() this type is incorrect because:
- the same struct is used for the new and the old expression
- the type of the new expression is adjusted before cast_value()
is called.
Fix this by adjusting the type of the new expression only after
cast_value() has been called.
