Giel van Schijndel 595390497c Add constexpr support
Ensuring that:
 * it still works as before on C++98 and C++03
 * C++11 "strict" constexpr is used where possible
  - requires replacing { R x; return f(x); } with { return f(R()); }
 * C++14 "relaxed" constexpr is used only where otherwise impossible
  - assignment operators
  - functions who's implementations require more than a single return
