Change the interface to expose the new information and deal with the enormous fallout.
Introduce the new ExceptionSpecificationType value EST_DynamicNone to more easily deal with empty throw specifications.
Update the tests for noexcept and fix the various bugs uncovered, such as lack of tentative parsing support.

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.

source-location information. We don't actually preserve this
information in any of the resulting TypeLocs (yet), so it doesn't
matter.

This successfully performs constructor lookup and verifies that a
delegating initializer is the only initializer present.
This does not perform loop detection in the initialization, but it also
doesn't codegen delegating constructors at all, so this won't cause
runtime infinite loops yet.

UnresolvedUsingValueDecl to use NestedNameSpecifierLoc rather than the
extremely-lossy NestedNameSpecifier/SourceRange pair it used to use,
improving source-location information.
Various infrastructure updates to support NestedNameSpecifierLoc:
- AST/PCH (de-)serialization
- Recursive AST visitor
- libclang traversal (including the first tests of this
functionality)
llvm-svn: 126459
nested-name-specifiers throughout the parser, and provide a new class
(NestedNameSpecifierLoc) that contains a nested-name-specifier along
with its type-source information.
Right now, this information is completely useless, because we don't
actually store the source-location information anywhere in the
AST. Call this Step 1/N.

* Flag indicating 'we're parsing this auto typed variable's initializer' moved from VarDecl to Sema
* Temporary template parameter list for auto deduction is now allocated on the stack.
* Deduced 'auto' types are now uniqued.

the parser will complete the declarator with a valid decl and thus trigger
delayed diagnostics for it. It certainly looks like we were intentionally
returning null here, but I couldn't find any good reason for it, and there
wasn't a comment, so farewell to all that.

access-control diagnostics which arise from the portion of the declarator
following the scope specifier, just in case access is granted by
friending the individual method. This can also happen with in-line
member function declarations of class templates due to templated-scope
friend declarations.
We were really playing fast-and-loose before with this sort of thing,
and it turned out to work because *most* friend functions are in file
scope. Making us delay regardless of context exposed several bugs with
how we were manipulating delay. I ended up needing a concept of a
context that's independent of the declarations in which it appears,
and then I actually had to make some things save contexts correctly,
but delay should be much cleaner now.
I also encapsulated all the delayed-diagnostics machinery in a single
subobject of Sema; this is a pattern we might want to consider rolling
out to other components of Sema.
