RISC-V: Use dominance analysis in global vsetvl elimination

I found that it's more reasonable to use existing dominance analysis.

gcc/ChangeLog:

* config/riscv/riscv-vsetvl.cc (pass_vsetvl::global_eliminate_vsetvl_insn):
Use dominance analysis.
(pass_vsetvl::init): Ditto.
(pass_vsetvl::done): Ditto.
