libstdc++: Make byte-sized std::fill_n a constant expression (PR 94933)
The overload for byte types uses memset and isn't constexpr. This adds
the specifier and uses std::is_constant_evaluated() to provide a
compile-time alternative.
PR libstdc++/94933
* include/bits/stl_algobase.h (__fill_a1): Make overload for byte types
usable in constant expressions.
* testsuite/25_algorithms/fill_n/constexpr.cc: Test with bytes and
non-scalars.
