    libstdc++: Add std::numeric_limits<__float128> specialization [PR104772]

    As suggested by Jakub in the PR, this just hardcodes the constants with
    a Q suffix, since the properties of __float128 are not going to change.

    We can only define it for non-strict modes because the suffix gives an
    error otherwise, even in system headers:

    limits:2085: error: unable to find numeric literal operator 'operator""=
Q'

    libstdc++-v3/ChangeLog:

            PR libstdc++/104772
            * include/std/limits (numeric_limits<__float128>): Define.
            * testsuite/18_support/numeric_limits/128bit.cc: New test.=
