rdar://155639885 It’s been requested that we be able to test different compaction configurations before we ship them. The envvar bmalloc_DynamicallyCompactTZoneAllocations=1 should randomly — for the time being set based on the TZone seed — cause a subset of types to be allocated out of compact-heaps.
