Matti Linnanvuori 8d7b52dfc9 atomic_ops.txt has incorrect, misleading and insufficient information [Bug 9020] ...

atomic_ops.txt has incorrect, misleading and insufficient information about
semantics of initializer, atomic_set, atomic_read and atomic_xchg.

It also incorrectly implies that operations mentioned above are not actual
atomic operations.

Included is most of the patch Document non-semantics of atomic_read() and
atomic_set() by Chris Snook, except the word "assignment".
