Improve support for out-of-line definitions of nested templates and
their members, including member class template, member function
templates, and member classes and functions of member templates.
To actually parse the nested-name-specifiers that qualify the name of
an out-of-line definition of a member template, e.g.,
template<typename X> template<typename Y>
X Outer<X>::Inner1<Y>::foo(Y) {
return X();
}
we need to look for the template names (e.g., "Inner1") as a member of
the current instantiation (Outer<X>), even before we have entered the
scope of the current instantiation. Since we can't do this in general
(i.e., we should not be looking into all dependent
nested-name-specifiers as if they were the current instantiation), we
rely on the parser to tell us when it is parsing a declaration
specifier sequence, and, therefore, when we should consider the
current scope specifier to be a current instantiation.
Printing of complicated, dependent nested-name-specifiers may be
somewhat broken by this commit; I'll add tests for this issue and fix
the problem (if it still exists) in a subsequent commit.
