Sounds good. Please go ahead and commit this if you have commit access - otherwise let me know & I'll commit it for you.

Have you tested whether 'check-llvm' passes if a user is enabling this feature through the environment variable? (ie: they don't cause any accidental failures in FileCheck tests not expecting this output?) & also that enabling this feature via the environment variable does work - passing down through the build system, lit, etc (ie: inject a deliberate failure somewhere in LLVM & see if the failure prints out all the input)?
