Not related to this CL, I'm a bit confused with these branches. Would it be
probably better to reorder the branches like this?

if (block.HasCaught()) {
  exceptionState.rethrowV8Exception();
  return;
}
if (value.IsEmpty() || value->IsUndefined()) {
  // Do nothing.
} else if (value->IsNull()) {
  impl.resetMember();
} else {
  impl.setMember();
}

You can address it in a follow-up CL.
