db203fb12b Amc no longer keeps statistics about pages condemned and retained. if we need this kind of analysis, it would be better to add more telemetry until we can do the analysis offline.

78507d9df6 Ensure that the amcss test case uses a wide range of arena grain sizes (by scaling up the whole allocation). 
Remove hack from rnd_grain -- this was covering up a bug.
Base the AMC "large" segment determination on the requested object size, not the (rounded up) segment size.
Assert in the case where largeSize < extendBy: this has bad space performance.
