Kevin Svetlitski 36ca0c1b7d Stop concealing pointer provenance in phn_link_get
At least for LLVM, [casting from an integer to a pointer hides provenance information](https://clang.llvm.org/extra/clang-tidy/checks/performance/no-int-to-ptr.html)
and inhibits optimizations. Here's a [Godbolt link](https://godbolt.org/z/5bYPcKoWT)
showing how this change removes a couple unnecessary branches in
`phn_merge_siblings`, which is a very hot function. Canary profiles show
only minor improvements (since most of the cost of this function is in
cache misses), but there's no reason we shouldn't take it.

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.
