RISC-V: Simplify codes of changing vsetvl instruction

This patch is NFC patch. I move these code as a function since we will
reuse it in the following patch (Refine phase 3 of VSETVL PASS)

gcc/ChangeLog:

* config/riscv/riscv-vsetvl.cc (change_vsetvl_insn): New function.
(pass_vsetvl::compute_global_backward_infos): Simplify codes.
