This was stored in LiveIntervals, but not actually used for anything related to LiveIntervals. It was only used in one check for if a load instruction is rematerializable. I also don't think this was entirely correct, since it was implicitly assuming constant loads are also dereferenceable. Remove this and rely only on the invariant+dereferenceable flags in the memory operand. Set the flag based on the AA query upfront. This should have the same net benefit, but has the possible disadvantage of making this AA query nonlazy. Preserve the behavior of assuming pointsToConstantMemory implying dereferenceable for now, but maybe this should be changed.
