    c++ frontend: initialize ivdep value
    
    Should control enter the switch from one of the cases other than
    the IVDEP one then the variable remains uninitialized.
    
    This fixes it by initializing it to false.
    
    gcc/cp/ChangeLog:
    
            * parser.cc (cp_parser_pragma): Initialize to false.
