  -----------
  [RISCV][VLOPT] Add support for widening integer mul-add instructions (#112219)

This adds support for these instructions and also tests getOperandInfo
for these instructions as well. I think the VL on the using add
instruction can be optimized further, once we add support for optimizing
non-vlmax.
