[SIOF] detect which variables need initialization Summary: - do a semantic analysis of each variable initializer to figure out if they need initialization - add a flag to globals that is true when they are `constexpr`. In that case, no analysis is needed as the user + compile guarantee that it is a compile-time constant. Reviewed By: sblackshear Differential Revision: D4081273 fbshipit-source-id: 44dbe29
