Currently the basic {cmp,}xchg() definitions live in the middle of the
atomic_t definitions. Let's pull them earlier so that the file has, in
order:
* __atomic_op_<order>() definitions
* {cmp,}xchg() definitions
* atomic_t definiitions
* atomic64_t definitions
* atomic_long_t definitions
... which will make subsequent rework less messy.
There should be no functional change as a result of this patch.
