arm: Add support for RCpc load-acquire instructions (ARMv8.3)

Please note that at the moment these instructions behave like the
existing load-acquire instructions, which follow the more conservative
RCsc consistency model. This means that the new instructions are
_functionally_ correct, but the potential performance improvements
enabled by the RCpc model will not be experienced in timing
simulations.
