Jingyue Wu 8d959dd563 Add the extracted constant offset using GEP
Fixed a TODO in r207783.

Add the extracted constant offset using GEP instead of ugly
ptrtoint+add+inttoptr. Using GEP simplifies future optimizations and makes IR
easier to understand. 

Updated all affected tests, and added a new test in split-gep.ll to cover a
corner case where emitting uglygep is necessary.
