[C++0x PATCH] "long long" support in C++0x mode

["Doug Gregor" <doug dot gregor at gmail dot com>]

C++0x has support for C99's "long long". This trivial patch enables
"long long" support in C++0x mode by turning off the warnings
generated by uses of "long long" in the preprocessor and C++ parser.
It doesn't get much easier than that :)

htdocs patch also included, so we document this change.

Tested i386-apple-darwin-8.11.1, no regressions. Okay for mainline?

	* c-opts.c (sanitize_cpp_opts): Don't warn about "long long" when
	in C++0x mode.

	* parser.c (cp_parser_check_decl_spec): Don't warn about "long
	long" in C++0x mode; change the warning to note that "long long"
	is only unsupported in C++98 mode.
