I landed some performance improvements for the Swift type checker recently, and I'm currently finishing up the next set of changes which I hope to merge soon.

There are two main improvements. The first is a new "disjunction pruning" optimization to help skip impossible overload choices, and the second set of improvements concern implicit conversions and the constraints they generate.
