RISC-V: Support VLS basic operation auto-vectorization

This patch support VLS modes auto-vectorization to enhance VLA auto-vectorization when niters is known. Consider this following case: void __attribute__ ((noinline, noclone)) \ PREFIX##_##TYPE##NUM (TYPE *__restrict a, TYPE *__restrict b, TYPE *__restrict c) \ { \ for (int i = 0; i < NUM; ++i) \ a[i] = b[i] OP c[i]; \ } DEF_OP_VV (plus, 16, int8_t, +) Before this patch: plus_int8_t16(signed char*, signed char*, signed char*): li a5,16 csrr a4,vlenb bleu a5,a4,.L2 mv a5,a4 .L2: vsetvli zero,a5,e8,m1,ta,ma vle8.v v2,0(a1) vle8.v v1,0(a2) vsetvli a4,zero,e8,m1,ta,ma vadd.vv v1,v1,v2 vsetvli zero,a5,e8,m1,ta,ma vse8.v v1,0(a0) ret After this patch: plus_int8_t16: vsetivli zero,16,e8,m1,ta,ma vle8.v v1,0(a2) vle8.v v2,0(a1) vadd.vv v1,v1,v2 vse8.v v1,0(a0) ret gcc/ChangeLog: * config/riscv/autovec-vls.md (<optab><mode>3): Add VLS modes. * config/riscv/vector-iterators.md: Ditto. * config/riscv/vector.md: Ditto. gcc/testsuite/ChangeLog: * gcc.target/riscv/rvv/autovec/vls/def.h: Add basic operations. * gcc.target/riscv/rvv/autovec/vls/and-1.c: New test. * gcc.target/riscv/rvv/autovec/vls/and-2.c: New test. * gcc.target/riscv/rvv/autovec/vls/and-3.c: New test. * gcc.target/riscv/rvv/autovec/vls/div-1.c: New test. * gcc.target/riscv/rvv/autovec/vls/ior-1.c: New test. * gcc.target/riscv/rvv/autovec/vls/ior-2.c: New test. * gcc.target/riscv/rvv/autovec/vls/ior-3.c: New test. * gcc.target/riscv/rvv/autovec/vls/max-1.c: New test. * gcc.target/riscv/rvv/autovec/vls/min-1.c: New test. * gcc.target/riscv/rvv/autovec/vls/minus-1.c: New test. * gcc.target/riscv/rvv/autovec/vls/minus-2.c: New test. * gcc.target/riscv/rvv/autovec/vls/minus-3.c: New test. * gcc.target/riscv/rvv/autovec/vls/mod-1.c: New test. * gcc.target/riscv/rvv/autovec/vls/mult-1.c: New test. * gcc.target/riscv/rvv/autovec/vls/plus-1.c: New test. * gcc.target/riscv/rvv/autovec/vls/plus-2.c: New test. * gcc.target/riscv/rvv/autovec/vls/plus-3.c: New test.
