Implement a 'lookupVisibleDecls' API similar to Clang's that replicates the UnqualifiedLookup logic for walking through a given scope looking for decls. Use it to populate the completion list in the repl.
Still to be done: Clang module lookup via Clang's lookupVisibleDecls, and context deduction from dotted path expressions.

While we haven't worked out the details of whether methods in
extensions can be overridden in Swift, it's something that does happen
in Objective-C, so we need to deal with it.
With this change, note that our demo application can both allocate
Objective-C objects with "new" (which John recently fixed) and also
subscript mutable arrays to both read and write.

functions. This involves a few steps:
- When assigning archetypes to type parameters, also walk all of the
protocols to which the type parameter conforms and assign archetypes
to each of the associated types.
- When performing name lookup into an archetype, look into all of
the protocols to which it conforms. If we find something, it can be
referenced via the new ArchetypeMemberRefExpr.
- When type-checking ArchetypeMemberRefExpr, substitute the values
of the various associated types into the type of the member, so the
resulting expression involves the archetypes for the enclosing
generic method.
The rest of the type checking essentially follows from the fact that
archetypes are unique types which (therefore) have no behavior beyond
what is provided via the protocols they conform to. However, there is
still much work to do to ensure that we get the archetypes set up
correctly.
