D93594 <https://reviews.llvm.org/D93594> depend on the dominate tree and loop information. It increased
the compile time when build wih -O0. However this is just to amend the
dominate tree and loop information, so that it is unnecessary to
re-analyze them again. Given the dominate tree of loop information are
absent in this pass, we can avoid to amending them.
