Summary: This fixes a bug in clang-format where the last line's penalty is not taken into account when its ending is broken. Usually the last line's penalty is handled by addNextStateToQueue, but in cases where the trailing `*/` is put on a newline, the contents of the last line have to be considered for penalizing.
