[NewPassManager] Pass the -fdebug-pass-manager flag setting into the Analysis managers to match what we do in opt

[craig.topper]

Summary

Currently the -fdebug-pass-manager flag for clang doesn't enable the debug logging in the analysis managers. This is different than what the switch does when passed to opt.

LGTM, nice catch!

Maybe update one of the new PM tests to check that this debug printing is available? =D
