Kindly ping. Please note that this is the first step to move aarch64-type-promotion pass to CGP (https://reviews.llvm.org/D28680). Once we move the aarch64-type-promotion pass to CGP, I want to sink sext when foldable in user GEPs (https://reviews.llvm.org/D28701) which improved 3% in spec2006/astar.
