David Malcolm ac81cf0b2b libcpp: Tweak to missing #include source location
This patch tweaks the error message location for missing header files.

Previously these read:

test.c:1:17: fatal error: 404.h: No such file or directory
 #include "404.h"
                 ^
compilation terminated.

With this patch, the pertinent string is underlined:

test.c:1:10: fatal error: 404.h: No such file or directory
 #include "404.h"
          ^~~~~~~
compilation terminated.

gcc/testsuite/ChangeLog:
	* c-c++-common/missing-header-1.c: New test case.
	* c-c++-common/missing-header-2.c: New test case.
	* c-c++-common/missing-header-3.c: New test case.
	* c-c++-common/missing-header-4.c: New test case.

libcpp/ChangeLog:
	* directives.c (do_include_common): Pass on "location" to
	_cpp_stack_include.
	* errors.c (cpp_diagnostic): Reimplement in terms of...
	(cpp_diagnostic_at): New function.
	(cpp_error_at): New function.
	(cpp_errno_filename): Add "loc" param and use it by using
	cpp_error_at rather than cpp_error.
	* files.c (find_file_in_dir): Add "loc" param and pass it to
	open_file_failed.
	(_cpp_find_file): Add "loc" param.  Use it to convert calls to
	cpp_error to cpp_error_at, and pass it to find_file_in_dir and
	open_file_failed.
	(read_file_guts): Add "loc" param.  Use it to convert calls to
	cpp_error to cpp_error_at.  Pass it to cpp_errno_filename.
	(read_file): Add "loc" param.  Pass it to open_file_failed and
	read_file_guts.
	(should_stack_file): Add "loc" param.  Pass it to read_file.
	(_cpp_stack_file): Add "loc" param.  Pass it to should_stack_file.
	(_cpp_stack_include): Add "loc" param.  Pass it to
	_cpp_find_file and _cpp_stack_file.
	(open_file_failed): Add "loc" param.  Pass it to
	cpp_errno_filename.
	(_cpp_fake_include): Add 0 as a source_location in call to
	_cpp_find_file.
	(_cpp_compare_file_date): Likewise.
	(cpp_push_include): Likewise for call to _cpp_stack_include.
	(cpp_push_default_include): Likewise.
	(_cpp_save_file_entries): Likewise for call to open_file_failed.
	(_cpp_has_header): Likewise for call to _cpp_find_file.
	* include/cpplib.h (cpp_errno_filename): Add source_location
	param.
	(cpp_error_at): New declaration.
	* init.c (cpp_read_main_file): Add 0 as a source_location in calls
	to _cpp_find_file and _cpp_stack_file.
	* internal.h (_cpp_find_file): Add source_location param.
	(_cpp_stack_file): Likewise.
	(_cpp_stack_include): Likewise.
