Richard Smith 17ee3ed9b7 Track a resolved Member on each member access expression. (#1333)
Type checking now stores information on a member access identifying the member that was accessed, not only its name. This parallels what we do for other similar constructs whose meaning is resolved by name lookup or type-checking, and will allow us to avoid redoing lookups in some cases during interpretation.
