8a094c1bf7 Amc no longer keeps statistics about pages condemned and retained. if we need this kind of analysis, it would be better to add more telemetry until we can do the analysis offline.

47110d4316 Mmqa test harness improvements: 
* Don't compile for profiling (not needed at the moment)
* Compile with -Wno-unused -Wno-missing-prototypes on OS X (so that argerr/146.c and similar test cases will build).
* Output conclusion for the first failing result (in alphabetical order), rather than whatever comes out of the hash table first.
* Don't gather symbols from block comments, otherwise we can't specify results like "assertcond = mps_pool_o != NULL" as MMQA will think that mps_pool_o is a missing symbol.

dddab0caf3 Fix mmqa test function/136.c: 
* Turn off the spare memory on the MVFF pool so that it returns freed memory to the arena immediately.
* Allocate something in the MV pool initially so that the span and block pools have some capacity.
* Stop the test if there isn't room in the MVFF to allocate 2 big blocks.
* Change the test success criterion so that it passes on 64-bit.

The restriction that "buffered allocation can't allocate across segment boundaries" no longer affects MVFF as the pool no longer uses segments.
