5c8e6891bb Update mmqa tests to cope with the removal of mv: 
* Fix typo in argerr/41.c.
* Delete argerr/43.c and argerr/44.c: MVFF doesn't take a maximum size argument so we can't test for erroneous values of this argument.
* Fix assertion condition in conerr/59.c.
* In function/136.c, need to specify extend-by for second pool, now that it's an MVFF pool.
* function/224.c now passes (fragmentation is avoided because MVFF allocations can cross extent boundaries).

7e0675d595 Fix mmqa function test cases so that they run on windows. in detail: 
1. On w3i6mv, int and long are 32 bits, so these types can't be used to hold a size_t or an mps_word_t. See 26.c, 38.c, 47.c, 66.c, 123.c, 136.c, 164.c, 165.c, 200.c, 203.c, 204.c, 205.c, 206.c, 207.c, 215.c, 223.c.
2. The Windows command line doesn't cope with parentheses. See 170.c.
3. The natural platform alignment is 16 bytes on w3i6mv, so allocations into pools using the default alignment need to be rounded up. See 21.c, 22.c, 203.c, 204.c, 205.c.
4. Microsoft Visual C/C++ is fussy about signed/unsigned comparison. See 226.c.
5. windows.h defines a SIZE macro so you can't use it as a parameter. See 232.c.

2bdef084ba Avoid warnings when compiling argerr/{146,147,148}.c with gcc. 
Test cases conerr/{53,54}.c rely on junk in uninitialized local variables, so ensure that there is some.
Test case function/72.c relies on an object moving, but it might be pinned by an ambiguous reference from the stack, so don't register the stack as a root.

f0eb2eb500 Speed up mmqa test cases by reducing iterations. additionally: 
* Take test options as parameters=.
* Rename BLAH to VERBOSE.
* Clearer reporting of slotHigh, arenaHigh, firstFit options to MVFF.
* Report times in seconds (not centiseconds).
* Reduce the commit limit exponentially and stop when too small.
* Ramp entering/leaving probabilities are scaled by iterations.
