[PATCH] D32720: [LICM] Introduce a finer granularity option to compute early exits.

[Daniel Berlin via llvm-commits]

I'm going to split off your OrderedInstructions part and iterate on it if
you don't mind.
I'd like to clean up PredicateInfo and a few other use cases (and kill all
the existing users/remove the Use API in Dominators, and just leave a note
to use OrderedInstructions)
