I have been unable to come up with a test that shows any change (I may check LNT to see if something changes), so ideas are welcome here.
However I'd expect this function return true (at least for now in RISC-V) for every instruction created in `RISCVInstrInfo::storeRegToStackSlot`. Conceptually (not part of the current patch) like this.
