[PATCH, BINUTILS, AARCH64, 3/9] Add instruction SB for ARMv8.5-A
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 instruction is retrospectively made optional for all versions of
the architecture from ARMv8.0 to ARMv8.4 and is mandatory from
ARMv8.5. Hence a new command line option of "+sb" is added for older
architectures.
