[PATCH v6 7/9] RISC-V: autovec: Verify that GET_MODE_NUNITS is a multiple of 2.

While working on autovectorizing for the RISCV port I encountered an issue where can_duplicate_and_interleave_p assumes that GET_MODE_NUNITS is a evenly divisible by two. The RISC-V target has vector modes (e.g. VNx1DImode), where GET_MODE_NUNITS is equal to one. Tested on RISCV and x86_64-linux-g
