[Debugify] Print the output to stderr Currently debugify prints it's output to stdout, with this patch all the output generated goes to stderr. This change lets us use debugify without taking away the ability to pipe the output to other llvm tools. llvm-svn: 332642

[Debugify] Tighten up the test for -debugify-each, NFC In post-commit review for r332416, Paul Robinson pointed out that the test for -debugify-each is not checking what it needs to. This commit tightens up the test. llvm-svn: 332497

[Debugify] Add -debugify-each for testing each pass in a pipeline This adds a -debugify-each mode to opt which, when enabled, wraps each {Module,Function}Pass in a pipeline with logic to add, check, and strip synthetic debug info for testing purposes. This mode can be used to test complex pipelines for debug info bugs, or to collect statistics about the number of debug values & locations lost throughout various stages of a pipeline.

[Debugify] Add a quiet mode to suppress warnings Suppressing warning output and module dumps significantly speeds up fuzzing with `opt -debugify-each`. llvm-svn: 334117

[Debugify] Don't apply DI before the bitcode writer pass 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
