RISCV makes all fixed vector MVTs with size less than or equal
to a command line option legal.

This didn't include v1f16 because it was missing but did include v1f32 and v1f64.

One test is affectd where we did test this type, but it is a horizontal
reduction so it is non-sensical. Perhaps we should canonicalize that
away somewhere.

I'm not sure if we should be making v1 types legal, but this will at
least make RISCV consistent across all types.
