This is mostly a no-op other than for ARM where it adds missing
__aeabi_mem* and __aeabi_*divmod functions. Even on ARM these will remain
unused until the rest of the ARM EABI code is merged.

*
* atomic.c defines a set of functions for performing atomic accesses on
* arbitrary-sized memory locations. This design uses locks that should
* be fast in the uncontended case, for two reasons:
*
* 1) This code must work with C programs that do not link to anything
* (including pthreads) and so it should not depend on any pthread
* functions.
* 2) Atomic operations, rather than explicit mutexes, are most commonly used
* on code where contended operations are rate.
*
* To avoid needing a per-object lock, this code allocates an array of
* locks and hashes the object pointers to find the one that it should use.
* For operations that must be atomic on two locations, the lower lock is
* always acquired first, to avoid deadlock.
*
