This patch fixes some issues with the RORB pseudo instruction.
- A minor issue in which the instructions were said to use the SREG, which is not true.
- An issue with the BLD instruction, which did not have an output operand.
- A major issue in which invalid instructions were generated. The fix also reduce RORB from 4 to 3 instructions, so it's also a small optimization.
These issues were flagged by the machine verifier.
