Philip Reames a4b45c28a1 [RISCV] Allow fractional LMUL for reduction start value
For reductions, we need to put the start value into a source vector. For fractional LMULs, we can perform the operation at the original LMUL.  For LMUL > 1, we eventually want to use a scalar insert, but that's outside the scope of this patch.
