New constraint handling
New constraint handling scheme using constraints that distinguish more between
parameter and non-parameter bounds and which track parameter bounds separately.
This allows a co-inductive formulation of satisfiability checking without fishy
cyclicity checks. It should also scale better for long chains of dependent type
variables.
