Re: [PATCH v4 05/10] RISC-V:autovec: Add autovectorization patterns for binary integer operations

[Michael Collison]

Hi Kito,

I will remove the unused UNSPECs, thank you for finding them.
I removed the include of "vector-iterators.md" because "riscv.md" 
already includes it and I was receiving multiple definition errors.

Why remove this?
