When unification of two types succeeds and at least one of them is an interface, we must be more cautious about when to accept the unification, to avoid order dependencies and unexpected inference results. The changes are localized and only affect matching against interfaces; they further restrict what are valid unifications (rather than allowing more code to pass). We may be able to remove some of the restriotions in a future release. See comments in code for a detailed description of the changes. Also, factored out "asInterface" functionality into a function to avoid needless repetition in the code. Fixes #60933. Fixes #60946.
