re PR c/48088 (-Werror=frame-larger-than=100 does not work as expected)

	PR c/48088
	PR c/68657
	* common.opt (Wframe-larger-than=): Add Warning.
	* opts.h (control_warning_option): Add ARG argument.
	* opts-common.c (cmdline_handle_error): New function.
	(read_cmdline_option): Use it.
	(control_warning_option): Likewise.  Add ARG argument.
	If non-NULL, decode it if needed and pass through

	CLVC_BOOLEAN.
	* opts.c (common_handle_option): Adjust control_warning_option
	caller.
	(enable_warning_as_error): Likewise.
c-family/
