[Arm, 2/3] Add instruction SB for AArch32
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/exploration-tools)
This patch adds the instruction SB. 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 "+sb" for older archtectures.
