We resolve guard patterns' guards in `resolve_pattern_inner`, so to avoid resolving them multiple times, we must avoid doing so earlier. To accomplish this, `LateResolutionVisitor::visit_pat` contains a case for guard patterns that avoids visiting their guards while walking patterns. This fixes an ICE due to `visit::walk_pat` being used instead, which meant guards at the top level of a pattern would be visited twice.
