    libstdc++: Fix std::span constraint for sizeof(size_t) < sizeof(int)
[PR108221]

    The default constructor has a constraint that is always false if
    arithmetic on size_t values promotes to int. Rewrite the constraint
    exactly as written in the standard, which works correctly.

    libstdc++-v3/ChangeLog:

            PR libstdc++/108221
            * include/std/span (span::span()): Un-simplify constraint to
            work for size_t of lesser rank than int.=
