Fixed a bug in type narrowing for pattern matching in the negative (fall-through) case when the subject type contains an Any. This addresses #5492. (#5499)

Fixed a recent regression that resulted in unsolved type arguments when a "bare" generic class (like dict) is passed as an argument to a function that accepts a type[T]. This addresses #5392. (#5494)

Added code to handle pathological case in unannotated code that writes to the same variable hundreds of times with different types. This mitigates the performance problem reported in #5475. (#5493)

Issue5405 5406 (#5470) 
* Improved assignment mismatch errors to better handle the case where the two types have the same short name but different fully-qualified names. In this case, the types are now expanded to avoid confusion. This addresses #5406.

* Fixed incorrect type mismatch error messages within constraint solver logic. The source and destination types were swapped, which led to confusing messages. This addresses #5405.
