This seems to be more of a Clang thing rather than a generic LLVM thing, so this moves it out of LLVM pipelines and as Clang extension hooks into LLVM pipelines. Move the post-inline EEInstrumentation out of the backend pipeline and into a late pass, similar to other sanitizer passes. It doesn't fit into the codegen pipeline. Also fix up EntryExitInstrumentation not running at -O0 under the new PM. PR49143 Reviewed By: hans Differential Revision: https://reviews.llvm.org/D97608
