testsuite/lib/multline.exp: show test name and line numbers

gcc/testsuite/ChangeLog:
	* lib/multiline.exp (_multiline_expected_outputs): Update comment.
	(dg-end-multiline-output): Capture line numbers within
	_multiline_expected_outputs.
	(handle-multiline-outputs): Access global $testname_with_flags
	and add it as a prefix to pass/fail results.  Extract line numbers
	from $_multiline_expected_outputs and print them within pass/fail
	results, replacing the printing of $index.  Consolidate the
	string prefix shared between pass/fail into a new local ($title).
