Make the InjectedClassNameType the canonical type of the current instantiation
of a class template or class template partial specialization. That is to
say, in
template <class T> class A { ... };
or
template <class T> class B<const T*> { ... };
make 'A<T>' and 'B<const T*>' sugar for the corresponding InjectedClassNameType
when written inside the appropriate context. This allows us to track the
current instantiation appropriately even inside AST routines. It also allows
us to compute a DeclContext for a type much more efficiently, at some extra
cost every time we write a template specialization (which can be optimized,
but I've left it simple in this patch).

Improve source-location information in a C++ typeid (type) expression
by using TypeSourceInfo, cleaning up the representation
somewhat. Teach getTypeOperand() to strip references and
cv-qualifiers, providing the semantic view of the type without
requiring any extra storage (the unmodified type remains within the
TypeSourceInfo). This fixes a bug found by Boost's call_traits test.
Finally, clean up semantic analysis, by splitting the ActOnCXXTypeid
routine into ActOnCXXTypeId (the parser action) and two BuildCXXTypeId
functions, which perform the semantic analysis for typeid(type) and
typeid(expression), respectively. We now perform less work at template
instantiation time (we don't look for std::type_info again) and can
give better diagnostics.
