We might generate a SwitchOnGeneratorState bytecode with zero jump table entries if the JS code only has dead suspension points (where AST suspensions are emitted, so suspend_count() > 0, but the bytecode for the suspension ends up not being emitted because it's dead). An example would be: async function() { return; await 0; } In these cases, we can skip emitting the generator prologue, since the function is not resumable.
