99bca8b5e2 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.

85f3d6bbb4 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.

78d5f049f0 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.

zcoll:

  - Park, to avoid all those minor collections.  Explanatory comments.

  - AMCTraceEnd: c Segs/Pages Whiten/Reclaim, cPagesRet(ained)
  - AMCTraceEnd_perc: percentage of condemned pages retained by ambig refs
  - AMCTraceEnd_pad_med: over-detailed calculations of Gain & Loss for Medium segs,
    requiring knowledge of size of obj1 in each seg.
diag.c:
  - Just show AMCTraceEnd_perc and AMCTraceEnd_pad_med, for zcoll/BigdropSmall's purposes.
Note: poolamc.c now has several episodes of experimental diagnostic in it.
It's time to re-baseline it from an un-hacked version.
