    libstdc++: Strip cv-qualifiers in std::atomic<FP> (PR 95282)

    This squashes two commits, r11-674 and r11-1401.

            PR libstdc++/95282
            * include/bits/atomic_base.h (__atomic_impl::load): Add
            const-qualifier to parameter so that _Tp is deduced as the
            non-const type, and use _Val to get the unqualified type.
            (__atomic_impl::exchange): Use the _Val alias to remove
            volatile from the reinterpret_cast result type.
            * testsuite/29_atomics/atomic_float/95282.cc: New test.
