Kadir Cetinkaya fd019ed54e [clang] Make handling of unnamed template params similar to function params
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.

Ben Langmuir fd6e39c40b [index] Add indexing for unresolved-using declarations
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".

Richard Smith 43a833bec4 Check that template template arguments match template template parameters
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.

Argyrios Kyrtzidis f66cef7575 [libclang] Use same USR encoding for 'class' as 'struct'.
'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.

Argyrios Kyrtzidis d06ce400c2 [libclang] Function templates can be 'overloaded' by return type, so encode the return type in the USR

Benjamin Kramer 3a7cc81d52 Report a correct end location for nameless parameters.
Ranges before:

Ranges after:

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

Douglas Gregor a9aa29cf0b Implement libclang support for using declarations. Clang actually uses
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.

    explicit instantiation.
  - Include template specialization arguments in the USRs for class

  - Cursor kinds for template parameters, with visitation logic

  locations
  - USR generation for function templates, template specialization
  types, template parameter types.

Also happens to fix PR7804, which I tripped across while testing.
