da626d1bc6 Because of the requirement to make popped objects dead in a timely fashion, we can only implement lightweight pops to an address in the buffer. in particular we can't support pending pops, which means that there's no need for the fields in the allocation point that support pending pops.

b06795251e Fix scanning/walking for snc: 
Record which segments are free and don't walk them (objects in these segments are dead).
If a buffered segment has a pending pop, don't scan or walk objects beyond the address that's going to be popped to (these objects are also dead).
Don't try to do a lightweight pop to an address that's not in the segment attached to the buffer -- the segment being popped to (and any other segments on the stack in between) are now dead, and the only way to mark them as being dead is to do a heavyweight pop.

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.
