  Log:
  Fix a range check bug. Don't left-shift the integer argument 'data'.
  Sign extension happens after the shift, not before so that boundary
  cases like 0x40000000 will not be caught properly.
  Instead, right shift ndirty. It is guaranteed to be a multiple of 8.
  While here, do some manual code motion and code commoning.
