0cf1718af9 Improve performance of mvff in hot builds by: 
1. Using macros to bypass PoolFree and Land* generic functions.
2. Compiling out assertions on functions on the critical paths for manual allocation and freeing.
3. Taking advantage of the fact that splay->updateNode does not change during a splay operation.

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.

3d1db4eab6 Use cbs subclasses to implement the fast-find and find-in-zones features. this avoids the need to control behaviour by passing booleans, and it means that there is no wasted space in the cbs block structure when these features are not used.

bcea6812fc 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).

c94be13bdf Improved support for pelles c: 
* Refactor nmake files so that a compiler-specific makefile is included; move Microsoft Visual C-specific options to mv.nmk.
* Add nmake files for Pelles (w3i3pc.nmk and pc.nmk).
* Rename spw3i3mv.c to spw3i3.c and spw3i6mv.c to spw3i6.c since these are also used by Pelles C.
* Make reasonable changes to the source code to avoid warnings from Pelles C:
** check results of function calls;
** avoid useless return values;
** undef max before defining it;
** ensure printf formats are checkable;
** move notreached() assertions to the end of blocks;
** suppress warnings in cases where the code shouldn't be changed ("Unreachable code", "Inline assembly code is not portable", "Structured Exception Handling is not portable").
