Revert "simplify CBR-CBR on the same condition"
The commit 7cd2ce022575 ("simplify CBR-CBR on the same condition")
added a generalization of the existing CBR-CBR simplification
using the dominance tree.
The problem is that as soon as a change is made to the CFG, the
dominance tree become invalid and should be rebuilt (which is costly
to do for each CFG changes) or updated (which is quite complex).
So, for now, revert this commit.
