a8d9fcc694 Design.mps.ring.naming: "when one structure parent contains one ring of child structures, the field in parent is usually known as childring, and the field in child is known as parentring". so the field in chunkstruct should be named arenaring.

2d0f425428 Ensure that code of the form if (condition) statement; is split over two lines, so that it is possible to set a breakpoint on the statement in a debugger. 
This change was agreed in 1997 (see <https://info.ravenbrook.com/project/mps/mail/1997/08/19/13-44/0.txt>), so it's about time it was implemented.

6b47c948ce set control_extend_by to 32768. 
The CONTROL_EXTEND_BY value for the extend by on the control pool was set really small (4096) on the assumption that the control pool was not heavily used. However, since we allocate Seg's in the control pool and recycle them frequently, this assumption is no longer true.

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.
