    libgcov: use proper type for n_functions
    
    gcov_info::n_functions type is initialized by generated
    code in build_info_type:
    
    /* n_functions */
    field = build_decl (BUILTINS_LOCATION, FIELD_DECL, NULL_TREE,
                        get_gcov_unsigned_t ());
    
    It uses gcov_unsigned_t, but the struct definition in libgcov.h uses
    unsigned type. That brings troubled on 16-bit targets.
    
            PR gcov-profile/105535
    
    libgcc/ChangeLog:
    
            * libgcov.h (struct gcov_info): Use gcov_unsigned_t for
            n_functions.
