Minor: ensure we only load the bigcall data once.
Add a by-hand mimic of the bigcall test... but this one works in both versions
Add a quickcheck property that tests that the Par and Seq versions of Infer yield the same answer
Bump lvish submodule version.
Add USE_LAYERED option.
Debugging with sam.  Added new test cases.  FIxed a nasty bug in CaseFun handling.  Everything but the cycle detection seems to work for Infer.hs now.
Merge branch 'master' of github.com:iu-parfunc/subtyping-haskell
Add seen set to infer.hs just like in de00c379d780261
