Need to explore whether this might cause any problem!

My intuition is that this should be fine in the case where we are generating the LIR op from the MIR op. IIRC, the reason we don't do this for every LIR op is that there are cases (especially where one MIR op can lower to several different LIR ops) where we don't trivially know the name of the corresponding MIR op. That shouldn't be a problem here.
