[ThinLTO, NewPM] Run OptimizerLastEPCallbacks from buildThinLTOPreLinkDefaultPipeline -O1 and above do dont call real optimizer pipeline in ThinLTO PreLink. Also clang can't add PostLink OptimizerLastEPCallbacks for in-process ThinLTO. This results in missing sanitizer passes with ThinLTO. Simple working solution is just call OptimizerLastEPCallbacks at the end of buildThinLTOPreLinkDefaultPipeline. Differential Revision: https://reviews.llvm.org/D96320
