        Description

        From: Felix Yang <felix.yang@linaro.org>

        Currently, the C2 peephole optimization is only enabled by default for x86 & aarch64 port.
        But we don't have any peephole rules for aarch64 port, scanning the instruction stream
        in PhasePeephole::do_transform does not make sense but a waste of time for this port.
