bpo-29941: Assert fixes (#886) (#956)
Make a non-Py_DEBUG, asserts-enabled build of CPython possible. This means
making sure helper functions are defined when NDEBUG is not defined, not
just when Py_DEBUG is defined.
Also fix a division-by-zero in obmalloc.c that went unnoticed because in
Py_DEBUG mode, elsize is never zero.
(cherry picked from commit a00c3fd12d421e41b769debd7df717d17b0deed5 and 06bb4873d6a9ac303701d08a851d6cd9a51e02a3)
