Vasileios Kalintiris b04672cade [mips] Define patterns for the atomic_{load,store}_{8,16,32,64} nodes.
Summary:
Without these patterns we would generate a complete LL/SC sequence.
This would be problematic for memory regions marked as WRITE-only or
READ-only, as the instructions LL/SC would read/write to the protected
memory regions correspondingly.
