for code like this:
   template<template<typename T> class U> class V {};

The problem is that the DeclPrinter assumed all TemplateDecls
have a getTemplatedClass(), but template template params don't
(so we got a NULL dereference).  The solution is to detect if
we're a template template param, and construct the template
class name ('class U') specially in this case.

Also, add a FIXME to add support for floating point value types.

Note that this is a move -- we pretend that we were really looking
at the unqualified typeloc all along -- rather than a recursion, so
we don't follow the normal CRTP plan of going through
getDerived().TraverseTypeLoc.  If we did, we'd be traversing twice
for the same type (once as a QualifiedTypeLoc version of the type,
once as an UnqualifiedTypeLoc version of the type), which in effect
means we'd call VisitTypeLoc twice with the 'same' type.  This
solves that problem, at the cost of never seeing the qualified
version of the type (unless the client subclasses
TraverseQualifiedTypeLoc themselves).  It's not a perfect solution.
A perfect solution probably requires making QualifiedTypeLoc a
wrapper around TypeLoc -- like QualType is a wrapper around Type*
-- rather than being its own class in the type hierarchy.

For TagType and TemplateSpecializationType, isDependent calculation may be invalid because some decls that the
calculation is using may still be initializing.
Thus, store the isDependent flag to PCH and restore directly to Type.

Doug, is this a reasonable compromise? I'd lean toward making it a normal
