When using jemalloc, malloc() needs to use TSD, while libpthread initialization needs malloc(). Having ___pthread_self set early to some static storage allows TSD to work early, thus allowing jemalloc and libpthread to initialize together. This incidentaly simplifies __pthread_enable/disable_asynccancel and __pthread_self, now that ___pthread_self is always initialized.
