    RISC-V: Add missing vsetvl instruction type.
    
    When implementing built-in framework, I notice I missed
    vsetvl instruction type, so add it in a single patch
    preparing for the following patches.
    
    gcc/ChangeLog:
    
            * config/riscv/riscv.md: Add vsetvl instruction type.
