PR/54307: Rin Okuyama: Lots of jemalloc assertions in latest -current

Workaround for random crash of userland binaries, as reported in
PR port-alpha/54307.

If rtree.c and tcache.c are compiled with -O0, userland just works
without problems as far as I can see. Alternately, you can specify
-DJEMALLOC_DEBUG to avoid random crash. Smells like compiler bug,
or wrong coding which relies on some undefined behavior.

Anyway, we need to pull this up into netbsd-9 asap.

Describe workaround for PR port-alpha/54307.

Describe that both GCC 7.4 and 8.3 fail in the last entry.
