options: wire up options-urls.cc into gcc_urlifier

Changed in v2:
- split out from the code that generates options-urls.cc
- call the generated function, rather than use a generated array
- pass around lang_mask

	* diagnostic.h (diagnostic_make_option_url_cb): Add lang_mask
	param.
	(diagnostic_context::make_option_url): Update for lang_mask param.

	* gcc-urlifier.h (make_gcc_urlifier): Add lang_mask param.
	* gcc.cc (driver::global_initializations): Pass 0 for lang_mask
	to make_gcc_urlifier.
	* opts-diagnostic.h (get_option_url): Add lang_mask param.
	* opts.cc (get_option_html_page): Remove special-casing for
	analyzer and LTO.
