libcpp: Improve location for macro names [PR66290]

When libcpp reports diagnostics whose locus is a macro name (such as for
-Wunused-macros), it uses the location in the cpp_macro object that was
stored by _cpp_new_macro. This is currently set to pfile->directive_line,
which contains the line number only and no column information. This patch
changes the stored location to the src_loc for the token defining the macro
name, which includes the location and range information.

libcpp/ChangeLog:

	PR c++/66290
	* macro.cc (_cpp_create_definition): Add location argument.
	* internal.h (_cpp_create_definition): Adjust prototype.
	* directives.cc (do_define): Pass new location argument to
	_cpp_create_definition.
	(do_undef): Stop passing inferior location to cpp_warning_with_line;
	the default from cpp_warning is better.
	(cpp_pop_definition): Pass new location argument to
	_cpp_create_definition.
	* pch.cc (cpp_read_state): Likewise.

gcc/testsuite/ChangeLog:

	PR c++/66290
	* c-c++-common/cpp/macro-ranges.c: New test.
	* c-c++-common/cpp/line-2.c: Adapt to check for column information
	on macro-related libcpp warnings.
