libstdc++: Ensure __builtin_constant_p isn't lost on the way

The more expensive code path should only be taken if it can be optimized
away.

libstdc++-v3/ChangeLog:

* include/experimental/bits/simd.h
(_SimdWrapper::_M_is_constprop_none_of)
(_SimdWrapper::_M_is_constprop_all_of): Return false unless the
computed result still satisfies __builtin_constant_p.
