This patch adds support for associating a diagnostic message with an
optional diagnostic_metadata object, so that plugins can add extra data
to their diagnostics (e.g. mapping a diagnostic to a taxonomy or coding
standard such as from CERT or MISRA).

Currently this only supports associating a CWE identifier with a
diagnostic (which is what I'm using for the warnings in the analyzer
patch kit), but adding a diagnostic_metadata class allows for future
growth in this area without an explosion of further "warning_at"
overloads for all of the different kinds of custom data that a plugin
might want to add.

This version of the patch renames the overly-general
-fdiagnostics-show-metadata to -fdiagnostics-show-cwe and adds test
coverage for it via a plugin.

It also adds a note to the documentation that no GCC diagnostics
currently use this; it's a feature for plugins (and, at some point,
I hope, the analyzer).

this->X::~X() is handled by finish_class_member_access_expr and its
lookup_destructor subroutine; let's use it in cp_parser_lookup_name for the
case where this-> is implicit.

I tried replacing the other destructor code here with just the call to
lookup_destructor, but that regressed handling of naming the destructor
outside a non-static member function.

	* parser.c (cp_parser_lookup_name): Use lookup_destructor.
	* typeck.c (lookup_destructor): No longer static.
