1. Speed up exhaustiveness checker. …

   Results in 5x faster builds on our app.
   
   Successive patterns on data constructors like tuples can cause the list
   of unhandled patterns to grow exponentially.
   
   This commit de-duplicates entries in the unhandled patterns list. This
   tames the exponential growth considerably.
   
   The proper solution is to create a real union type for nitpicking
   patterns. There’s still quite a bit of speed improvement available.
