Philip Reames 963f36ed4a [AtomicExpand] Allow libcall expansion for non-zero address spaces (try 2) ...

Restore a reverted commit, with the silly mistake fixed.  Sorry for the previous breakage.  

Be consistent about how we treat atomics in non-zero address spaces.  If we get to the backend, we tend to lower them as if in address space 0.  Do the same if we need to insert a libcall instead.
