For 'x::template y', consistently give a "no member named 'y' in 'x'"
diagnostic if there is no such member, and give a 'template keyword not
followed by a template' name error if there is such a member but it's not a
template. In the latter case, add a note pointing at the non-template.
Don't suggest inserting a 'template' keyword in 'X::Y<' if X is dependent
if the lookup of X::Y was actually not a dependent lookup and found only
non-templates.

template arguments.
This fixes some cases where we'd incorrectly accept "A::template B" when B is a
kind of template that requires template arguments (in particular, a variable
template or a concept).

compiler is run in a mode where the default C++ standard is newer than C++03.
The reason is because one of the warnings checked is only produced when the
compiler is using C++03 or lower.
This change fixes this problem as well as adds explicit run lines to run the
test in C++03 and C++11 modes.

Previously Clang would simply ignore the 'template' keyword in this case.

Other compilers accept invalid code here that we reject, and we need a
better error message to try to convince users that the code is really
incorrect. Consider:
class Foo {
typedef MyIterHelper<Foo> iterator;
friend class iterator;
};
Previously our wording was "elaborated type refers to a typedef".
"elaborated type" isn't widely known terminology, so the new diagnostic
says "typedef 'iterator' cannot be referenced with class specifier".

This is a fix for https://llvm.org/bugs/show_bug.cgi?id=25561 which was a
crash on invalid. Change the handling of invalid decls to have a catch-all
case to prevent unexpecting decls from triggering an assertion.

disambiguation keywords outside of templates in C++98/03. Previously,
the warning would fire when the associated nested-name-specifier was
not dependent, but that was a misreading of the C++98/03 standard:
now, we complain only when we're outside of any template.

ParseOptionalCXXScopeSpecifier() only annotates the subset of
template-ids which are not subject to lexical ambiguity. Add support
for the more general case in ParseUnqualifiedId() to handle cases
such as A::template B().
Also improve some diagnostic locations.
Fixes PR7030, from Alp Toker!

declaration, we can end up with template-id annotation tokens for
types that have not been converted into type annotation tokens. When
this is the case, translate the template-id into a type and parse as
an expression.

- This is designed to make it obvious that %clang_cc1 is a "test variable"
which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
can be useful to redefine what gets run as 'clang -cc1' (for example, to set
a default target).
