LDDRdPtrQ was marked as `earlyclobber`, which doesn't play well with GreedyRA (which can generate this instruction through `loadRegFromStackSlot()`). This seems to be the same case as: https://github.com/llvm/llvm-project/blob/a99b912c9b74f6ef91786b4dfbc25160c27d3b41/llvm/lib/Target/AVR/AVRInstrInfo.td#L1421 Closes #81911.
