nit: Can we re-order this calculation slightly? This would make it in line with
the calculation of args.arguments and also easier to parse IMHO. I was thinking
about the following order:

value = frame_ptr + StandardFrameConstants::kCallerSPOffset -
    (output_frame_size - output_frame_offset) + kPointerSize;

Done.

+      StandardFrameConstants::kCallerSPOffset + kPointerSize;
   output_frame->SetFrameSlot(output_frame_offset, value);
   if (trace_) {
     PrintF("    0x%08" V8PRIxPTR ": [top + %d] <- 0x%08"
