Chuck Jordan f1874fabdd arc: do lr and sr instructions together, avoid instruction pipeline bubble
The lr and sr instructions cause a pipeline bubble. There is an efficiency
to be gained if pairs of lr or sr instructions are done right next to
each other. This can avoid some stall cycles.
Also, r14 and r15 can be used with isa-16 instructions.
