(This replaces #121740. Sorry for wasting your time.) This is a follow-up to a previous commit (ee7ca0d) which eliminated several "TODO: make CombinerHelper methods const" remarks. As promised in that ealier commit, this change completes the set by also making the methods of AMDGPUCombinerHelper const so that the Helper member of AMDGPUPreLegalizerCombinerImpl can be const rather than explicitly mutable.
