RISC-V: Fix infinite compilation of VSETVL PASS
This patch fixes issue reported by Jeff.
Testing is running. Ok for trunk if I passed the testing with no regression ?
gcc/ChangeLog:
* config/riscv/riscv-vsetvl.cc (pre_vsetvl::emit_vsetvl): Fix inifinite compilation.
(pre_vsetvl::remove_vsetvl_pre_insns): Ditto.
