Reviewed by Keith Miller.
Currently, we're only applying this max check to
CompleteSubspace::tryAllocateSlow.
We found that adding it to LocalAllocator::allocateSlowCase can cause crashes
due to failed
Structure allocations (which are fatal). As a result, the testing disruption
from those crashes
far outweigh any benefits we currently get from it. So, we'll leave the max
check out of
LocalAllocator::allocateSlowCase for now.
