	(mep_option_override): Move register handling for -mivc2 from
	mep_handle_option.  Use global_options_set.x_mep_tiny_cutoff
	instead of option_mtiny_specified.
	(mep_handle_option): Access target_flags via opts pointer.  Don't
	assert that global structures are in use.  Defer part of -mivc2
	handling and move it to mep_option_override.
