Move EntryExitInstrumenter(PostInlining=true) to as late as possible and EntryExitInstrumenter(PostInlining=false) to an early pre-inlining stage (but skip for ThinLTO post-link). This should fix the issues reported in https://github.com/rust-lang/rust/issues/92109 and https://github.com/llvm/llvm-project/issues/52853. These are caused by https://reviews.llvm.org/D97608.
