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.

* c-format.c (format_warning_at_char): Pass UNKNOWN_LOCATION
rather than NULL to format_warning_va.
