  1. Speed type argument checking 

    The upper bound is usually `object`, so add a fast path and skip a
potentially slow subtype check if that's the case. Also make type
annotations more precise.

This seems to at least speed up type checker tests, by 1-2% or so.
This also potentially speeds up self-check a bit, though probably by
less than 1%.
