46f52b028f 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.

23f518054b Add space for future expansion [1]. While here clean up a little, spsr is 
only 32-bits, and mark the holes in the struct with a pad member.
