I also rewrote merge1 and merge2 which are dangerous functions to touch.

c140d690fc First draft of cross-module type checking
Currently, all top-level types are imported. No alias resolution
happens so you need to use "import open M" atm.

807076ad57 Add CSaveEnv, optimize CAnd, make it prettier
CSaveEnv is a special constraint that indicates that the current
environment should be saved for later use.

(/\) now optimizes away arguments that are already CTrue.
