Printing typedefs or type aliases using clang_getTypeSpelling() is missing the
namespace they are defined in. This is in contrast to other types that always
yield the full typename including namespaces.

Under this defect resolution, the injected-class-name of a class or class
template cannot be used except in very limited circumstances (when declaring a
constructor, in a nested-name-specifier, in a base-specifier, or in an
elaborated-type-specifier). This is apparently done to make parsing easier, but
it's a pain for us since we don't know whether a template-id using the
injected-class-name is valid at the point when we annotate it (we don't yet
know whether the template-id will become part of an elaborated-type-specifier).
As a tentative resolution to a perceived language defect, mem-initializer-ids
are added to the list of exceptions here (they generally follow the same rules
as base-specifiers).
When the reference to the injected-class-name uses the 'typename' or 'template'
keywords, we permit it to be used to name a type or template as an extension;
other compilers also accept some cases in this area. There are also a couple of
corner cases with dependent template names that we do not yet diagnose, but
which will also get this treatment.

Previously type/storage qualifiers would not be annotated as the declaration they belonged to.
Just use the resulting source range of getRawCursorExtent() which is more correct
than what AnnotateTokensWorker::Visit() was adjusting it to.

I had to force -fno-delayed-template-parsing on some Index tests because delayed template parsing will change the output of some tests.

3 lines of code and improve a bunch of information in the libclang view
of the code.
Updates the two tests that exercise this with the new data, checking
that each new source location actually points back to the declared
template parameter.

template arguments. I believe that this is the last place in the AST
where we were storing a source range for a nested-name-specifier
rather than a proper nested-name-specifier location structure. (Yay!)
There is still a lot of cleanup to do in the TreeTransform, which
doesn't take advantage of nested-name-specifiers with source-location
information everywhere it could.

template specialization types. This also required some parser tweaks,
since we were losing track of the nested-name-specifier's source
location information in several places in the parser. Other notable
changes this required:
- Sema::ActOnTagTemplateIdType now type-checks and forms the
appropriate type nodes (+ source-location information) for an
elaborated-type-specifier ending in a template-id. Previously, we
used a combination of ActOnTemplateIdType and
ActOnTagTemplateIdType that resulted in an ElaboratedType wrapped
around a DependentTemplateSpecializationType, which duplicated the
keyword ("class", "struct", etc.) and nested-name-specifier
storage.
- Sema::ActOnTemplateIdType now gets a nested-name-specifier, which
it places into the returned type-source location information.
- Sema::ActOnDependentTag now creates types with source-location
information.

template specialization types. There are still a few rough edges to
clean up with some of the parser actions dropping
nested-name-specifiers too early.

nested-name-speciciers within elaborated type names, e.g.,
enum clang::NestedNameSpecifier::SpecifierKind
Fixes in this iteration include:
(1) Compute the type-source range properly for a dependent template
specialization type that starts with "template template-id ::", as
in a member access expression
dep->template f<T>::f()
This is a latent bug I triggered with this change (because now we're
checking the computed source ranges for dependent template
specialization types). But the real problem was...
(2) Make sure to set the qualifier range on a dependent template
specialization type appropriately. This will go away once we push
nested-name-specifier locations into dependent template
specialization types, but it was the source of the
valgrind errors on the buildbots.

information for qualifier type names throughout the parser to address
several problems.
The commit message from r126737:
Push nested-name-specifier source location information into elaborated
name types, e.g., "enum clang::NestedNameSpecifier::SpecifierKind".
Aside from the normal changes, this also required some tweaks to the
parser. Essentially, when we're looking at a type name (via
getTypeName()) specifically for the purpose of creating an annotation
token, we pass down the flag that asks for full type-source location
information to be stored within the returned type. That way, we retain
source-location information involving nested-name-specifiers rather
than trying to reconstruct that information later, long after it's
been lost in the parser.
With this change, test/Index/recursive-cxx-member-calls.cpp is showing
much improved results again, since that code has lots of
nested-name-specifiers.

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.

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).

- Recursive AST visitor
- libclang traversal (including the first tests of this
functionality)
