e50fdb0f73 Instead of creating one padding object for each reclaimed object in a nailed amc segment, create a padding object for each contiguous run of reclaimed objects, speeding up any future traversals of the segment.

cb150cd014 More assertions in dylan object format: 
1. the limit of a padding object must be greater than its base
2. mustn't forward padding objects
(These assertions would have helped us with job003848.)

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.
