This change introduces a notion of type "size" as a way to detect and avoid degenerate type inference cases. The examples found by the fuzzer can create large, complex types that result in hangs during type inference. Much like the type inference recursion limit, this size limit is a heuristic that is unlikely to be hit during normal use of the language but prevents crashes or hangs during extreme usage such as with generated code that incurs artificially large or deeply nested types. Fixes #2369
