Make gcno more precise about BBs really belonging to a line (PR gcov-profile/79891).

PR gcov-profile/79891
* gcov.c (add_line_counts): Assign BBs to lines just if the BB
is marked by compiler as living on a line.
(get_cycles_count): Remove usage of the union.
(output_intermediate_file): Likewise.
(find_source): Fix GNU coding style.
(accumulate_line_counts): Remove old non-all block mode.
(output_lines): Remove usage of the union.
* profile.c (output_location): Include all BBs, even if
belonging to a same line (and file) as a previous BB.
