RISC-V: Change VSETVL PASS always call split_all_insns

Since LCM will destroy CFG, we are going to reorder the location of VSETVL PASS
at least before bbro (block-reorder PASS) which is before split3 PASS. We need
to call it in VSETVL PASS to get final RVV instructions patterns.

gcc/ChangeLog:

* config/riscv/riscv-vsetvl.cc (pass_vsetvl::execute): Always call split_all_insns.
