Sorry for not getting to this earlier.

It is not clear to me why compare debug actually compares discriminators
with and without debug info?  If debug info is off, the discriminators
are not output from the compiler so I think we could also simply disable
the pass computing them.

Discriminators of debug statements matter for the autoFDO feedback
quality, so it seems to me that correct fix would be to simply disable
discriminators for compare-debug comparison?  I had patch for that, will
re-implement it, but I wonder if there is something I miss.
