I assume we are testing things before we mainline drivers? |

Add JIT support for the load_acquire and store_release instructions. The
implementation is similar to the kernel where:
load_acquire => plain load -> lwsync
store_release => lwsync -> plain store
To test the correctness of the implementation, following selftests were
run:
