As of r256448, the C++ frontend underlines many bad arguments in its
diagnostics; those where perform_overload_resolution returns a
non-NULL candidate, but there's a failure in convert_like_real.
However, for the case where perform_overload_resolution fails, but
there's a single non-viable candidate, the error is diagnosed by
cp_build_function_call_vec, and that currently doesn't underline
the bad argument:
$ cat test.cc
void callee (int one, const char **two, int three);
void
caller (const char *fmt)
{
callee (1, fmt, 3);
}
We emit:
$ g++ test.cc
test.cc: In function 'void caller(const char*)':
test.cc:6:20: error: cannot convert 'const char*' to 'const char**' for argument '2' to 'void callee(int, const char**, int)'
callee (1, fmt, 3);
^
It's going through convert_for_assignment, and
implicitly using input_location.
This patch updates convert_for_assignment for this case, using
an EXPR_LOCATION if there is one, or falling back to input_location
otherwise, underlining the argument in question:
test.cc: In function 'void caller(const char*)':
test.cc:6:14: error: cannot convert 'const char*' to 'const char**' for argument '2' to 'void callee(int, const char**, int)'
callee (1, fmt, 3);

When compiling with -fconcepts,
cp_parser_template_declaration_after_export calls
cp_parser_template_introduction and that preparses qualified-ids not
preceded by typename in such a way that, when we get to
cp_parser_parse_and_diagnose_invalid_type_name and then
cp_parser_diagnose_invalid_type_name, the nested name specifier no
longer carries the previous template-dependent context, so we don't
stand a chance to suggest the use of 'typename' any more. Thus,
tolerate in the testcase the poorer error messages we get.

When an anon struct gets a name through a typedef, we reset its
linkage and that of its members. Member functions may get vague
linkage, which schedules them for deferred output, but we don't want
to add them to the queue if they're uninstantiated templates,
e.g. because the enclosing function is a template. They will be added
as needed when the enclosing template is instantiated.
