Log:
[FREELDR]: For *every single heap allocation*, there was code to request an entire *heap
statistic run*! This is ridiculous and slows heap allocations tremendously. Additionally,
it also assumes bstats was linked in, which it might not be if the flag wasn't set in
bheap.c. Only enable this code if a special MM_DBG define is set.
[FREELDR]: Done originally for ARM, but I think x86 will appreciate the benefit too (and
x86 can now go ahead and disable all those ridiculous debug settings that are turned on by
default in bheap.c).
