Jakob Stoklund Olesen 36d29bc723 Remove extra MayLoad/MayStore flags from atomic_load/store.
These extra flags are not required to properly order the atomic
load/store instructions. SelectionDAGBuilder chains atomics as if they
were volatile, and SelectionDAG::getAtomic() sets the isVolatile bit on
the memory operands of all atomic operations.

The volatile bit is enough to order atomic loads and stores during and
after SelectionDAG.

This means we set mayLoad on atomic_load, mayStore on atomic_store, and
mayLoad+mayStore on the remaining atomic read-modify-write operations.
