[RISCV] Fold (sext_inreg (setcc), i1) -> (sub 0, (setcc). (#154206)
This helps the 3 vendor extensions that make sext_inreg i1 legal.
I'm delaying this until after LegalizeDAG since we normally have
sext_inreg i1 up until LegalizeDAG turns it into and+neg.
I also delayed the recently added (sext_inreg (xor (setcc), -1), i1)
combine. Though the xor isn't likely to appear before LegalizeDAG anyway.
