In `PerformActionHelper`, use the unqualified type for lookup. In `PerformInstanceBinding`, propagate qualifiers to the unbound element type's class type when doing the `ConvertToValueOrRefOfType` conversion, and to the element type when forming the `ClassElementAccess` instr (except for `partial`, which is only used if the member being accessed is `base`). In handle_operator.cpp, prevent assignment to a reference to a const type.
