Title: Cleans up some TR code.

Adds cond-check-below, abstracting out a common pattern.

Removes special cases for - and fx-, adding test cases to show that the desired behavior still holds.

Moves special casing for vectors and structs into its own file.

I am trying to clean up the app code, so that I can eventually add better inference code.
