  [RISCV] fix RISCVPushPopOptimizer pass

RISCVPushPopOptimizer pass didn't suggest that CFI instructions can be
inserted between cm.pop and ret and couldn't apply optimization in these
cases. The patch fix it and allows the pass to remove CFI instructions and
combine cm.pop and ret into the one instruction: cm.popret or cm.popretz.
