Use the term MC/DC in help for gcov --conditions

Without key terms like "masking" and "MC/DC" it is not at all obvious
what --conditions actually reports on, and there is no easy path for the
user to figure out. By at least including the two key terms MC/DC and
masking users have something to search for.

gcc/ChangeLog:

	* gcov.cc (print_usage): Reference masking MC/DC.
