    Signed-off-by: Matthias Kretz <m.kretz@gsi.de>

    libstdc++-v3/ChangeLog:

            PR libstdc++/108856
            * include/experimental/bits/simd_builtin.h
            (_SimdImplBuiltin::_S_masked_unary): More efficient
            implementation of masked inc-/decrement for integers and floats
            without AVX2.
            * include/experimental/bits/simd_x86.h
            (_SimdImplX86::_S_masked_unary): New. Use AVX512 masked subtract
            builtins for masked inc-/decrement.=
