TBH, I feel "X is readonly and has side effects" sends the wrong message to begin with. It is a contradiction (in the IR world) as basically shown by the need for this patch. Given that there are no examples in-tree I don't understand why one would mark a side-effect intrinsic as readonly (or similar). Long story short, I would argue this should be a loud error, not silently ignored.

VPatBinary helps encode LMUL in the instruction name,
but for vrgatherei16 it needs to encode both LMUL & EMUL in the instruction name,
like PseudoVRGATHEREI16_VV_M1_M1, and PseudoVRGATHEREI16_VV_M1_M2.
