80% time for inference is spent in reflection #1

We wanted to save code when implementing this, so type inference uses reflection to transform data structures. It takes 85% of the 60-70s it now takes to generate code.

This is used to emulate shapeless's everywhere, which doesn't work inside cakes.

The main culprit is the call from onTypes to mapSubtrees.
