atomic.h: Fix build with clang
clang defines ATOMIC_SEQ_CST but its implementation of the
_atomic_exchange() builtin differs from that of gcc. Move the
_clang branch of the ifdef ladder to the top and fix its
implementation (there is no such builtin as __sync_exchange),
so we can compile with clang again.
