Split out the _acq and _rel functions. These were the same, but there is
no need for them to be this strong, we only need to provide one or the
other.

While here replace atomic_load_acq_* and atomic_store_rel_* with a single
instruction version, and fix the definition of atomic_clear_* to point to
the correct functions.
