Introduce CFGImplicitDtor::isNoReturn() to query whether a destructor actually returns.  Use this for -Wreturn-type to prune false positives reported in PR 6884.

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.

is a higher-level tool than ns_returns_retained &c.;  it lets users specify
that not only does a method have different retain/release semantics, but
that it semantically acts differently than one might assume from its name.
This in turn is quite useful to static analysis.

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.
