Daniel Micay 34b6754f70 enable CONFIG_STATS by default for Android
The tiny performance cost might as well be accepted now because this
will be needed for Android Q. It's also quite possible that some apps
make use of the features based on this including malloc_info.

Daniel Micay e0891c8cfc implement the option of large size classes
This extends the size class scheme used for slab allocations to large
allocations. This drastically improves performance for many real world
programs using incremental realloc growth instead of using proper growth
factors. There are 4 size classes for every doubling in size, resulting
in a worst case of ~20% extra virtual memory being reserved and a huge
increase in performance for pathological cases. For example, growing
from 4MiB to 8MiB by calling realloc in increments of 32 bytes will only
need to do work beyond looking up the size 4 times instead of 1024 times
with 4096 byte granularity.
