[PATCH V2] RISC-V: Refactor Phase 3 (Demand fusion) of VSETVL PASS

This patch refactors the Phase 3 (Demand fusion) and rename it into Earliest fusion. I do the refactor for the following reasons: 1. Current implementation of phase 3 is doing too many things which makes the code quality quite messy and not easy to maintain. 2. The demand fusion I do
