RISC-V: Add viota missed avl_type attribute
This patch fixes the following FAIL when LMUL = 8:
riscv-sim/-march=rv64gcv/-mabi=lp64d/-mcmodel=medany/--param=riscv-autovec-lmul=m8/--param=riscv-autovec-preference=scalable
FAIL: gcc.dg/vect/slp-multitypes-2.c execution test
The rootcause is we missed viota avl_type, so we end up with incorrect vsetvl configuration:
vsetvli zero,a2,e64,m8,ta,ma
viota.m v16,v0
'a2' value is a garbage value.
After this patch:
vsetvli a4,zero,e64,m8,ta,ma
viota.m v16,v0
gcc/ChangeLog:
* config/riscv/vector.md: Add viota avl_type attribute.
gcc/testsuite/ChangeLog:
* gcc.target/riscv/rvv/autovec/bug-2.c: New test.
