Now that we're recommending inlining with client code and optimising with -O2 or -O3, we can't afford any bug introduced by the strict aliasing rule.

arenavm.c -- move chunk-return into new function "VMCompact".
(also, in VMArenaFinish, null out arena->primary in VMArenaFinish, so it is not left dangling).
arena.c, arenavm.c, mpm.h, mpmst.h, mpmtypes.h:
arena->class->compact: ArenaCompact, ArenaTrivCompact, VMCompact
trace.c -- traceReclaim calls ArenaCompact!

tract.c -- fix more ChunkCache defects:
- drop never-read chunkCache->pageTableBase and pageTableLimit fields: they were used for ChunkOfSeg(), back when each SegStruct was actually a PageStruct is some chunk's PageStructTable; see VMArenaChunkOfSeg() in //info.ravenbrook.com/project/mps/branch/2001-08-13/trunk/src/arenavm.chttps://github.com/Ravenbrook/mps/issues/46
- there's no need for arena to initialise the chunk cache; this allows en/decache functions to be local to tract.c (ie. declared static)

Tracer calls PoolTraceEnd() when the trace is TraceFINISHED.
AbstractPoolClass uses PoolTrivTraceEnd -- a NOOP. [mpm.h, mpmst.h, mpmtypes.h, pool.c, poolabs.c]
AMC overrides with AMCTraceEnd, to emit diagnostic on how well the trace went! [poolamc.c]
