    • Use char_span for return type of location_get_source_line · 7761dfbe 
      location_get_source_line returns a const char * that isn't 0-terminated,
writing back a length through an int * param.

This is error-prone, as all call-sites have to take into account the
lack of 0-termination, and respect the length of the buffer.

It's cleaner to bundle together this pointer+length state into a class,
so this patch does so, reusing the "char_span" class that I introduced
in r250187 (as part of the fix for PR c/81405).

The patch also adds assertions to all access to the char_span.

gcc/c-family/ChangeLog:
	* c-format.c (get_corrected_substring): Update for
	location_get_source_line returning a char_span.  Use a char_span
	when handling the prefix of the correction.
	* c-indentation.c (get_visual_column): Update for
	location_get_source_line returning a char_span.
	(get_first_nws_vis_column): Likewise.

gcc/ChangeLog:
	* diagnostic-show-locus.c (layout::layout): Update for
	location_get_source_line returning a char_span.
	(struct char_span): Move to input.h.
	(struct correction): Update for fields in char_span becoming
	private.

	returning a char_span.

	* final.c (asm_show_source): Likewise.
	* input.c (location_get_source_line): Convert return type
	from const char * to char_span, losing the final "line_len"
	param.
	(dump_location_info): Update for the above.
	(get_substring_ranges_for_loc): Likewise.  Use a char_span
	when handling the literal within the line.
	(test_reading_source_line): Update for location_get_source_line
	returning a char_span.
	* input.h (class char_span): Move here from
	diagnostic-show-locus.c, converting from a struct to a class.
	Make data members private.
	(char_span::operator bool): New.

	(char_span::xstrdup): New.
	(location_get_source_line): Convert return type from const char *
	to char_span, losing the final "line_size" param.

gcc/testsuite/ChangeLog:
	* gcc.dg/plugin/diagnostic_plugin_test_show_locus.c
	(test_show_locus): Update for location_get_source_line returning a
	char_span.  Use char_span for handling words in the
	"test_many_nested_locations" fix-it example.
