[PATCH, BINUTILS, AARCH64, 4/9] Add Execution and Data Restriction instructions
This patch is part of the patch series to add support for ARMv8.5-A
extensions.
(https://developer.arm.com/products/architecture/cpu-architecture/a-profile/docs/ddi0596/a/a64-base-instructions-alphabetic-order)
This patch adds the prediction restriction instructions (that is, cfp,
dvp, cpp). These instructions are 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 which can be used
by the older architectures.
