[PATCH] RISC-V: Split arguments of expand_vec_perm

[juzhe . zhong]

From: Juzhe-Zhong <juzhe.zh...@rivai.ai>

Since the following patch will calls expand_vec_perm with
splitted arguments, change the expand_vec_perm interface in
this patch.

gcc/ChangeLog:

        * config/riscv/autovec.md: Split arguments.
        * config/riscv/riscv-protos.h (expand_vec_perm): Ditto.
        * config/riscv/riscv-v.cc (expand_vec_perm): Ditto.
