    Original change's description:
    > [compiler] Support acq/rel accesses and atomic accesses on tagged
    >
    > This CL adds an AtomicMemoryOrder parameter to the various atomic load
    > and store operators. Currently only acquire release (kAcqRel) and
    > sequentially consistent (kSeqCst) orders are supported.
    >
    > Additionally, atomic loads and stores are extended to work with tagged
    > values.
    >
    > This CL is a pre-requisite for supporting atomic accesses in Torque,
    > which is in turn a pre-requisite for prototyping shared strings.
