Andrew Trick c2c79c90f2 Rewrite LinearFunctionTestReplace to handle pointer-type IVs. ...

We've been hitting asserts in this code due to the many supported
combintions of modes (iv-rewrite/no-iv-rewrite) and IV types. This
second rewrite of the code attempts to deal with these cases systematically.
