locking/atomic/x86: Introduce the read64_nonatomic macro to x86_32 with cx8
As described in commit:
e73c4e34a0e9 ("locking/atomic/x86: Introduce arch_atomic64_read_nonatomic() to x86_32")
the value preload before the CMPXCHG loop does not need to be atomic.
Introduce the read64_nonatomic assembly macro to load the value from a
atomic_t location in a faster non-atomic way and use it in
atomic64_cx8_32.S.
