RISC-V: Support RVV permutation auto-vectorization
This patch supports vector permutation for VLS only by vec_perm pattern.
We will support TARGET_VECTORIZE_VEC_PERM_CONST to support VLA permutation
in the future.
Fixed following comments from Robin.
gcc/ChangeLog:
* config/riscv/autovec.md (vec_perm<mode>): New pattern.
* config/riscv/predicates.md (vector_perm_operand): New predicate.
* config/riscv/riscv-protos.h (enum insn_type): New enum.
(expand_vec_perm): New function.
* config/riscv/riscv-v.cc (const_vec_all_in_range_p): Ditto.
(gen_const_vector_dup): Ditto.
(emit_vlmax_gather_insn): Ditto.
(emit_vlmax_masked_gather_mu_insn): Ditto.
(expand_vec_perm): Ditto.
