        Description

        Previously discussed in the following two thread:
        https://mail.openjdk.java.net/pipermail/aarch64-port-dev/2019-April/007141.html
        https://mail.openjdk.java.net/pipermail/aarch64-port-dev/2019-April/007173.html

        Because C2 does not mask immediate shifts, there are other lurking bugs for the aarch64 port.
        It would be good to systematically mask all immediate shift counts throughout aarch64.ad in a separate patch.
