RISC-V: Add vwadd<u>/vwsub<u>/vwmul<u>/vwmulsu.vv lowering optimizaiton for RVV auto-vectorization
Base on V1 patch, adding comment:
;; Use define_insn_and_split to define vsext.vf2/vzext.vf2 will help combine PASS
;; to combine instructions as below:
;; vsext.vf2 + vsext.vf2 + vadd.vv ==> vwadd.vv
