Be more accurate when deducing where along the several usages of a binding it is constrained to be some type that is incompatible with an expectation.
This also renames the method to
note_source_of_type_mismatch_constraintbecause I prefer that name, though I guess I can revert that. (Also drive-by renamenote_result_coercion->suggest_coercing_result_via_try_operator, because it's suggesting, not noting!)This PR is (probably?) best reviewed per commit, but it does regress a bit only to fix it later on, so it could also be reviewed as a whole if that makes the final results more clear.
