5a604a2f51 Fixing bugs introduced by type puns passed through scanning methods, discovered by offsetting mps_ss_s from the beginning of scanstatestruct. 
Adding a pseudo-target "find-puns" which, on FreeBSD mostly, prints useful warnings about strict aliasing rule violations.
Fixing more strict aliasing rule violations found by the above.

78d5f049f0 Eliminating type puns on scan states, location dependencies, and allocation points through the mps interface. 
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.

61890da12b Fixing up occurences of "unsigned long" in the main mps and test code so that we no longer assume that "unsigned long" is large enough for a pointer or size, or that it's the longest available integer type, since these are not true on 64-bit windows.

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!

bf80a3a11d Mps br/padding: new pooltraceendmethod: do end-of-trace work 
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]
