[pushed] diagnostics: make m_lang_mask private

[David Malcolm]

No functional change intended.

Successfully bootstrapped & regrtested on x86_64-pc-linux-gnu.
Pushed to trunk as r14-5530-g4547c271c455dc.

gcc/ChangeLog:
	* diagnostic.cc (diagnostic_context::set_option_hooks): Add
	"lang_mask" param.
	* diagnostic.h (diagnostic_context::option_enabled_p): Update for
	move of m_lang_mask.
	(diagnostic_context::set_option_hooks): Add "lang_mask" param.
	(diagnostic_context::get_lang_mask): New.
	(diagnostic_context::m_lang_mask): Move into m_option_callbacks,
	thus making private.
	* lto-wrapper.cc (main): Update for new lang_mask param of
	set_option_hooks.
	* toplev.cc (init_asm_output): Use get_lang_mask.
	(general_init): Move initialization of global_dc's lang_mask to
	new lang_mask param of set_option_hooks.
