Improved bidirectional type inference in the case where the type and the expected type are generic but the expected type is a base class that has been specialized. For example, if the expected type is Mapping[str, int] and the type is a dict.

Fixed bug in logic that handles chained comparisons (e.g. "a < b < c"). The code was not properly handling the case where the left expression was parenthesized (e.g. "(a < b) < c").

Fixed bug where an f-string expression generated an error if it ended in an equal sign followed by whitespace. The Python 3.8 spec doesn't indicate whether whitespace is allowed here, but clearly the interpreter accepts it.

Augmented the reportIncompatibleMethodOverride diagnostic rule to check for cases where a non-function symbol within a subclass redefines a function symbol in a base class.

Made the reportIncompatibleMethodOverride rule smarter. It now properly handles position-only parameters and allows a subclass to extend the signature of a method it is overriding as long as the parameters are *varg, **kwarg, or have default values.
