Summary:
Clang uses the location identifier should be inserted for declarator
decls when a decl is unnamed. But for type template and template template
paramaters it uses the location of "typename/class" keyword, which makes it hard
for tooling to insert/change parameter names.
This change tries to unify these two cases by making template parameter
parsing and sourcerange operations similar to function params/declarator decls.

In dependent contexts we end up referencing these, so make sure they
have USRs, and have their declarations indexed. For the most part they
behave like typedefs, but we also need to worry about having multiple
using declarations with the same "name".

properly even when a non-type template parameter has a dependent type.
Previously, if a non-type template parameter was dependent, but not dependent
on an outer level of template parameter, we would not match the type of the
parameter. Under [temp.arg.template], we are supposed to check that the types
are equivalent, which means checking for syntactic equivalence in the dependent
case.
This also fixes some accepts-invalids when passing templates with auto-typed
non-type template parameters as template template arguments.

'class' and 'struct' can be used interchangebly for forward references.
Use the same encoding otherwise we may get into a weird situation where the USR for the same
declaration is different based on whether the definition of the tag reference is visible or not.

This does not change the actual location of the ParmVarDecl, it still
points to the location where the name would be. PR17970.

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

CXXConstructorExpr/CXXTemporaryObjectExpr references the constructor
it calls. Then, tweak clang_getCursor() to prefer such a call over a
type reference to the type being called.

more closely parallel the computation of linkage. This gets us to a state
much closer to what gcc emits, modulo bugs, which will undoubtedly arise in
abundance.

to an "overloaded" set of declarations. This cursor kind works for
unresolved references to functions/templates (e.g., a call within a
template), using declarations, and Objective-C class and protocol
forward declarations.

clang_getSpecializedCursorTemplate(), which determines the template
(or member thereof) that the given cursor specializes or from which it
was instantiated. This routine can be used to establish a link between
templates and their instantiations/specializations.

three different kinds of AST nodes to represent using declarations:
UsingDecl, UnresolvedUsingValueDecl, and
UnresolvedUsingTypenameDecl. These three are collapsed into a single
cursor kind for using declarations, since libclang clients don't need
the distinction.
Several related changes here:
- Cursor visitation of the three AST nodes for using declarations
- Proper source-range computation for these AST nodes
- Using declarations have no USRs, since they don't actually declare
any entities.

in a few related ways:
- Don't recurse into instantiations of templates.
- Recurse into explicit specializations.
- Visit the template arguments of an explicit specialization or
explicit instantiation.
- Include template specialization arguments in the USRs for class
template specializations.
llvm-svn: 112720
template. Such cursors occur, for example, in template specialization
types such as vector<int>. Note that we do not handle the
super-interesting case where the template name is unresolved, e.g.,
within a template.
llvm-svn: 112636
libclang. This includes:
- Cursor kind for function templates, with visitation logic
- Cursor kinds for template parameters, with visitation logic
- Visitation logic for template specialization types, qualified type
locations
- USR generation for function templates, template specialization
types, template parameter types.
Also happens to fix PR7804, which I tripped across while testing.
