apr_atomic: Generic apr_atomic_read64() needs a mutex on 32bit systems (tearing).
A 64bit load on a 32 bit CPU/system uses two instructions (tearing), so ensure
atomicity with regard to other atomic functions by using the (same) lock.
test_atomics_threaded64() fails because of this on 32bit systems. PR 66457.
* atomic/unix/mutex64.c(apr_atomic_read64):
Use locking when APR_SIZEOF_VOIDP < 8
