The functions all call foo and therefore need a stack frame what makes
them subject to shrink wrapping.  Also all the additional instructions
in the function body makes it fragile wrt instruction scheduling.  Just

The format_warning_at_substring API has a rather clunk way of indicating
the location of the pertinent param (if any): a source_range * is passed
in, which can be NULL.  Doing so requires extracting a range from the
location_t and passing around a pointer to it, or NULL, as needed.

This patch simplifies things by eliminating the source_range * in
favor of a location_t, with UNKNOWN_LOCATION used to signify that
no param location is available.

gcc/c-family/ChangeLog:
	* c-format.c (format_warning_at_char): Pass UNKNOWN_LOCATION
	rather than NULL to format_warning_va.
	(check_format_types): Likewise when calling format_type_warning.
	Remove code to extract source_ranges and source_range * in favor

	(format_type_warning): Convert source_range * param to a
