clean up "static" and "constexpr" types
- use `static constexpr inline' to avoid requiring explicit declarations in object code - use `const Foo* const' to maybe put into readonly binary segment (at least for ELF DSOs) - `constexpr' in function scope has storage, avoid `static' - don't use `constexpr' where there's no advantage, like arrays We'd like to avoid overhead of atomic initialization for each function call. No idea how `static constexpr' requiring storage in the standard plays with atomic initialization requirement. Hearsay points that `constexpr' without `static' in block scope behaves more to our liking. It's all hazy though. I'm not 100% sure if `static inline constexpr' has any storage. Hopefully none, like a #define, and stuff bigger than registers gets coalesced within the same module, with small stuff being immediates.
