…e, r=aliemjay Don't ICE when ambiguity is found when selecting `Index` implementation in typeck Fixes rust-lang#118111 The problem here is when we're manually "selecting" an impl for `base_ty: Index<?0>`, we don't consider placeholder region errors (leak check) or ambiguous predicates. Those can lead to us not actually emitting any fulfillment errors on line 3131.

Fixes #118111
The problem here is when we're manually "selecting" an impl for
base_ty: Index<?0>, we don't consider placeholder region errors (leak check) or ambiguous predicates. Those can lead to us not actually emitting any fulfillment errors on line 3131.
