Hamish Knight 30af99e47e [Completion] Better handle merging of lookup base types ...

For unresolved member completion, we were preferring
the more general type, when we ought to be preferring
the more specific type. Additionally, for both
unresolved member and postfix completion we were
opening archetypes, which doesn't work as expected
since we don't compare requirements. Factor out
the logic that deals with merging base types for
lookup, and have it prefer either the subtype, or
the optional type in the case of optional promotion.
