Ah. This all looks excellent! Currently jhc spends about 30-40% of its
time in the containers package according to profiling so improvements
there will notably speed up compilation. Though, I already modifed a lot
to use IntSets instead of Sets and independently discovered the
HashSet/HashMap trick, but the gain should still be signifigant. The
focus on tree-union is particularly cool, as I know a lot of that goes
on inside the compiler.
