[hanickadot]

SG1 Monday in ST. Louis:

Forward P3309 to LEWG with the following notes: Add constexpr to the wait and notify functions in the next revision of P3309 Atomic should be supported in constexpr whenever shared_ptr is supported in constexpr (whichever paper lands second should have this change) is_lock_free() should not be made constexpr
