Simple (hack or heuristic) resolution of some delegations to inherent impls
while correct resolution through ProbeContext is not available
during AST -> HIR lowering due to query cycles.
Successful resolutions from this heuristics are not a subset of
successful resolutions from the correct approach, if we want to stabilize
delegations to inherent impls with this approach we need a second pass in type checking
(i.e., when there’s no cycles) that makes sure that resolutions from
the heuristic match the correct resolutions, or report errors otherwise.
