    gcov: Add open mode parameter to gcov_do_dump()
    
    gcc/
    
            * gcov-tool.cc (gcov_do_dump): Add mode parameter.
            (gcov_output_files): Open files for reading and writing.
    
    libgcc/
    
            * libgcov-driver-system.c (gcov_exit_open_gcda_file): Add mode
            parameter.  Pass mode to gcov_open() calls.
            * libgcov-driver.c (dump_one_gcov):  Add mode parameter.  Pass mode to
            gcov_exit_open_gcda_file() call.
            (gcov_do_dump): Add mode parameter.  Pass mode to dump_one_gcov()
            calls.
            (__gcov_dump_one):  Open file for reading and writing.
