For all trivial and zero frame-sized functions, we now require an explicit NOFRAME annotation as the heuristic has changed. See go.dev/cl/466316. Most of these functions do not *require* NOFRAME, but this change encodes the existing behavior in order to avoid accidental bugs or regressions. PiperOrigin-RevId: 513946210
