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).
