Make sure that the dynamic lookup table has the right set of members.

Clean up the "can be accessed by dynamic lookup" predicate so that it
checks for a generic context. We no longer need to do the checking in
name lookup, since this means that the dynamic lookup table won't have
anything we can't use (thanks Jordan!). Drop the [objc] allowance for
members of a generic context: it still leaves us with a very weird
case of messaging something when we can't even figure out the type
that we think the object has.

Extend the walk searching for members to include inner classes within
structs, so we get all of the members globally.
