LookupVisibleDecls, unifying the name lookup mechanisms used by code
completion and typo correction. Aside from the software-engineering
improvements, this makes code-completion see through using directives
and see ivars when performing unqualified name lookup in an
Objective-C instance method.

provide completions for @ keywords. Previously, we only provided
@-completions after an @ was actually typed, which is useful but
probably not the common case.

Also, make sure a few Objective-C 2.0 completions only show up when
Objective-C 2.0 support is enabled (the default).

C++ grammatical constructs that show up in top-level (namespace-level)
declarations, member declarations, template declarations, statements,
expressions, conditions, etc. For example, we now provide a pattern
for

  static_cast<type>(expr)

when we can have an expression, or

  using namespace identifier;

when we can have a using directive.

Also, improves the results of code completion at the beginning of a
top-level declaration. Previously, we would see value names (function
names, global variables, etc.); now we see types, namespace names,
etc., but no values.

  tring str2;

we produce the following diagnostic + fix-it:

typo.cpp:15:1: error: unknown type name 'tring'; did you mean 'string'?
  tring str2;
  ^~~~~
  string


To make this really useful, we'll need to introduce typo correction in
many more places (wherever we do name lookup), and implement
declaration-vs-expression heuristics that cope with typos
better. However, for now this will handle the simple cases where we
already get good "unknown type name" diagnostics.

The LookupVisibleDecls functions are intended to be used by code
completion as well as typo correction; that refactoring will happen
later.

Remove isPod() from DenseMapInfo, splitting it out to its own
isPodLike type trait.  This is a generally useful type trait for
more than just DenseMap, and we really care about whether something
acts like a pod, not whether it really is a pod.
