DependentNameTypeLoc. Teach the recursive AST visitor and libclang how to
walk DependentNameTypeLoc nodes.

Also, teach libclang about TypedefDecl source ranges, so that we get
those. The massive churn in test/Index/recursive-cxx-member-calls.cpp
is a good thing: we're annotating a lot more of this test correctly
now.

- renames evalCastNL and evalCastL to evalCastFromNonLoc and
  evalCastFromLoc (avoid abbreviations that aren't well known).

- makes all function parameter names start with a lower case letter
  for consistency and distinction from member variables.

- avoids abbreviations in function parameter names.

UnresolvedLookupExpr and UnresolvedMemberExpr.

Also, improve the computation that checks whether the base of a member
expression (either unresolved or dependent-scoped) is implicit. The
previous check didn't cover all of the cases we use in our
representation, which threw off source-location information for these
expressions (which, in turn, caused some breakage in libclang's token
annotation).

The prototype for objc_msgSend() is technically variadic - 
`id objc_msgSend(id, SEL, ...)`. 
But all method calls should use a prototype that matches the method, 
not the prototype for objc_msgSend itself().

They cooperate in that NSErrorChecker listens for ImplicitNullDerefEvent events that
DereferenceChecker can dispatch.
ImplicitNullDerefEvent is when we dereferenced a location that may be null.

A checker can register as receiver/listener of "events" (basically it registers a callback
with a function getting called with an argument of the event type) and other checkers can
register as "dispatchers" and can pass an event object to all the listeners.
This allows cooperation amongst checkers but with very loose coupling.
