Jakob Stoklund Olesen dd364419ee Add ATOMIC_LDR* pseudo-instructions to model atomic_load on ARM. ...

It is not safe to use normal LDR instructions because they may be
reordered by the scheduler. The ATOMIC_LDR pseudos have a mayStore flag
that prevents reordering.

Atomic loads are also prevented from participating in rematerialization
and load folding.
