Summary: LTO and ThinLTO optimizes the IR differently. One source of differences is the amount of internalizations that can happen. Add an option to enable/disable internalization so that other differences can be studied in isolation. e.g. inlining. There are other things lto and thinlto do differently, I will add flags to enable/disable them as needed.
