divanorama 3de0c24859 Disable builtin malloc in tests 
With `--with-jemalloc-prefix=` and without `-fno-builtin` or `-O1` both clang and gcc may optimize out `malloc` calls
whose result is unused. Comparing result to NULL also doesn't necessarily count as being used.

This won't be a problem in most client programs as this only concerns really unused pointers, but in
tests it's important to actually execute allocations.
`-fno-builtin` should disable this optimization for both gcc and clang, and applying it only to tests code shouldn't hopefully be an issue.
Another alternative is to force "use" of result but that'd require more changes and may miss some other optimization-related issues.

This should resolve https://github.com/jemalloc/jemalloc/issues/2091

README 

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.

The INSTALL file contains information on how to configure, build, and install
jemalloc.

The ChangeLog file contains a brief summary of changes for each release.
