  [libc] Use `if constexpr` for compile-time conditionals (#113417)

Don't use plain `if` for things that are compile-time constants.
Instead, use `if constexpr`.  This both ensures that these are
properly wired up constant expressions as intended, and prevents
warnings from the compiler about useless `if` checks that look in
the source like they're meant to do something at runtime but will
just be compiled away.
