142787d3 - [RISCV][VLOPT] Add support for checkUsers when UserMI is a Single-Width Integer Reduction (#120345)

[RISCV][VLOPT] Add support for checkUsers when UserMI is a Single-Width Integer Reduction (#120345) Reductions are weird because for some operands, they are vector registers but only read the first lane. For these operands, we do not need to check to make sure the EEW and EMUL ratios match. The EEWs, however, do need to match.
