Rechecked.  I should have remembered given that I updated gas to improve
the handling of cache-control completers for PA 1.1 ;(  So, we should be
using the 'co' completer except in situations (if any) where the spinlock
is shared with a non-coherent I/O processor.  However, I believe that
PA 1.1 still has the 16-byte alignment requirement.

Need to look at the uses in GCC.
