[PATCH v2 1/1] RISC-V: Optimze the reverse conditions of rotate shift

From: wangfeng There is no Immediate operand of ins "rol" according to the B-ext, so the immediate operand should be loaded into register at first. But we can convert it to the ins "rori" or "roriw", and then one immediate load ins can be reduced. So I added some conditions when reverse the rotat
