    [Arm, 3/3] Add Execution and Data Prediction instructions for AArch32

    This patch is part of the patch series to add support for ARMv8.5-A


    This patch adds the Execution and Data Prediction Restriction
    instructions (that is, cfprctx, dvprxtc, cpprctx). These are all
    aliases to MCR and are disassembled as such.

    This instruction is retrospectively made optional for all versions of
    the architecture from ARMv8.0 to ARMv8.4 and is mandatory from
    ARMv8.5.  Hence adding a new +predres for older versions of the


The official name of the extension is v8.0-PredInv.
(You can see this used in the xml descriptions for the new insns, eg:
https://developer.arm.com/docs/ddi0595/b/aarch64-system-instructions/cfp-rctx )
