* Improve handling of partial applications involving casts
This patch improves prepareRhs, so that it deals better with casts.
We want to deal well cases like this
v = (f e1 `cast` co) e2
Here we want to make e1,e2 trivial and get
x1 = e1; x2 = e2; v = (f x1 `cast` co) v2
This really happens in parser libraries, which wrap functions in newtypes.
