e11e83d909 Amc can't omit the guard "segrankset(seg) != ranksetempty" for calling segsetgrey, because amcz uses segments with an empty rank set. 
It's OK to call SegSetGrey on a segment with an empty rank set so long as you are not actually setting it to be grey for any traces, so correct the AVER accordingly.

5df2620e49 Short-circuit the cases where we set the greyness or summary of a segment to the same as it was before in all cases, rather than just in a few restricted cases in amc. 
This was the result of noticing a large number of SetSetGrey events that set the segment to the same greyness when scanning ambiguous references.

dd039bfbdc Fixing bugs introduced by type puns passed through scanning methods, discovered by offsetting mps_ss_s from the beginning of scanstatestruct.

f748ad2b28 Eliminating type puns on scan states, location dependencies, and allocation points through the mps interface. 
Now that we're recommending inlining with client code and optimising with -O2 or -O3, we can't afford any bug introduced by the strict aliasing rule.

  - AMCTraceEnd_pad_med: over-detailed calculations of Gain & Loss for Medium segs,
