Currently, yields and awaits inside loops compile to bytecode which switches to the top of the loop header, and switch again once inside the loop. This is to make loops reducible. This replaces this switching logic with a single switch bytecode that directly jumps to the bytecode being resumed. Among other things, this allows us to no longer maintain the generator state after the switch at the top of the function, and avoid having to track loop suspend counts. TurboFan still needs to have reducible loops, so we now insert loop header switches during bytecode graph building, for suspends that are discovered to be inside loops during bytecode analysis. We do, however, do some environment magic across loop headers since we know that we will continue switching if and only if we reached that loop header via a generator resume. This allows us to generate fewer phis and tighten liveness.
