c968255f1e 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.

3a6a9e1101 Fix compilation of seg.c.
1. "#ifdef CHECKLEVEL > CheckLevelMINIMAL" was bogus: the #ifdef should have been #if, but even then it would not be right, because in the CHECKLEVEL_DYNAMIC configuration, CHECKLEVEL is a variable rather than a preprocessor constant. So use the condition defined(AVER_AND_CHECK_ALL) instead.
2. The final CHECKL(addr == seg->limit) only makes sense if the loop was executed.
3. The variables used by the loop need to be inside the #if to avoid warnings about unused variables.
4. Add reference to the job from a comment.

d3d2795fce Improve control over checking:
1. Where Type is a pointer type with a signature, replace CHECKL(TypeCheck(val)) with CHECKD(Type, val).
2. Where Type is a pointer type with no signature, replace CHECKL(TypeCheck(val)) with CHECKD_NOSIG(Type, val).
3. Where Type is a pointer type with a signature, but the structure is not visible at point of checking, replace CHECKL(TypeCheck(val)) with CHECKD_NOSIG(Type, val). Reference <design/check/#.hidden-type>
4. Make BTCheck extern and use it where possible.
5. Replace AVER(TypeCheck(val)) with AVERT(Type, val).

9bb6b2f8be Tidy-up of attributes and pool classes:
* Bring design up to date.
* New function PoolHasAttr encapsulates attribute checking.
* Abstract classes are abstract and mustn't be checked.
* The dummy pool class in fotest needs a size.
* Abstract pool classes null out methods that they can't provide a generic implementation for, to force subclasses to provide one.
* New function PoolTrivFramePopPending provides a generic implementation of that method.
* Rename PoolNoFreeWalk to PoolTrivFreeWalk since it has NOOP rather than NOTREACHED.
* Check that AttrMOVINGGC implies AttrGC.
* Remove unimplemented attributes (BUF_RESERVE, BUF_ALLOC, INCR_RB, INCR_WB, PM)
* AMC now inherits from AMCZ instead of the other way round. This is simpler: AMC adds features to AMCZ rather than AMCZ taking features away (and not quite getting it right).
* Similarly, LO inherits from AbstractSegBufPoolClass + PoolClassMixInCollect so that it doesn't have to clear AttrSCAN and the scan methods.
* Fix bug in MFSCheck -- mustn't check unroundedUnitSize >= UNIT_MIN since small unit sizes are rounded up to UNIT_MIN.
* Don't see AttrFREE in MRG (since no free method is supplied).
* Check AttrSCAN systematically (in PoolScan and SegCheck) rather than opportunistically in TraceStart and TraceQuantum.
