    Style/consistency/nano-optimization nit:  replace occurrences of
      (high_bits << PyLong_SHIFT) + low_bits with
      (high_bits << PyLong_SHIFT) | low_bits
    in Objects/longobject.c.  Motivation:
     - shouldn't unnecessarily mix bit ops with arithmetic ops (style)
     - this pattern should be spelt the same way thoughout (consistency)
     - it's very very very slightly faster: no need to worry about
       carries to the high digit (nano-optimization).
