Remove function signature rewriter.

trentxintong · trentxintong · commit 3f075dfe4755 · 2016-03-24T10:50:47.000-07:00
We decided to use the inliner to rewrite the caller's callsites.

And eventually I will turn FunctionSignatureAnalysis into a Utility.
As its data should only be used and kept in the cloner pass.
