Applying synthetic debug info before the bitcode writer pass has no testing-related purpose. This commit prevents that from happening. It also adds tests which check that IR produced with/without -debugify-each enabled is identical after stripping. This makes it possible to check that individual passes (or full pipelines) are invariant to debug info. llvm-svn: 333861
