Kevin Svetlitski 07a2eab3ed Stop over-reporting memory usage from sampled small allocations
@interwq noticed [while reviewing an earlier PR](https://github.com/jemalloc/jemalloc/pull/2478#discussion_r1256217261)
that I missed modifying this statistics accounting in line with the rest
of the changes from #2459. This is now fixed, such that sampled small
allocations increment the `.nmalloc`/`.ndalloc` of their effective bin
size instead of over-reporting memory usage by attributing all such
allocations to `SC_LARGE_MINCLASS`.

jemalloc is a general purpose malloc(3) implementation that emphasizes
fragmentation avoidance and scalable concurrency support.  jemalloc first came
into use as the FreeBSD libc allocator in 2005, and since then it has found its
way into numerous applications that rely on its predictable behavior.  In 2010
jemalloc development efforts broadened to include developer support features
such as heap profiling and extensive monitoring/tuning hooks.  Modern jemalloc
releases continue to be integrated back into FreeBSD, and therefore versatility
remains critical.  Ongoing development efforts trend toward making jemalloc
among the best allocators for a broad range of demanding applications, and
eliminating/mitigating weaknesses that have practical repercussions for real
world applications.

The COPYING file contains copyright and licensing information.
