libstdc++: More efficient masked inc-/decrement implementation

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.
