* config/i386/i386.c (ix86_isa_flags_explicit): Remove. 

	(ix86_handle_option): Access ix86_isa_flags and
	ix86_isa_flags_explicit via opts pointer.  Don't assert that
	global structures are in use.
	(ix86_function_specific_save, ix86_function_specific_restore):
	Update ix86_isa_flags_explicit field name.
	* config/i386/i386.opt (ix86_isa_flags_explicit): New Variable
	entry.
	(ix86_isa_flags_explicit): Rename TargetSave entry to
	x_ix86_isa_flags_explicit.
