Add TyCon Set/Env and use them in a few places.wip/andreask/tyConEnv
Firstly this improves code clarity.
But it also has performance benefits as we no longer
go through the name of the TyCon to get at it's unique.
In order to make this work the recursion check for TyCon
has been moved into it's own module in order to avoid import
cycles.
