There was no need to move this one out of compare_type_predicate_entailment except consistency with both compare_{method,const}_predicate_entailment which is reason enough imo.

On lifetime param mismatches, we ICE'd in tcx.type_of(trait_ct.def_id).instantiate(tcx, trait_to_impl_args) a few lines further up for obvious reasons. That's on me, I messed that up in the initial GCI PR.
