[PATCH] D110075: [LTO] [Legacy] Add -debug-pass-manager option to enable pass run/skip trace.

[Steven Wu via Phabricator via llvm-commits]

steven_wu added a comment.

I assume this is a debug option for LTO developer that is not going for production. That is why I said `LGTM` without a test case. I do think it will be good to set that in ThinLTOCodeGenerator as well, probably not needed for `llvm-lto2`.
