Restore the behavior of frame lowering before my refactoring.
It turns out that ppc backend has really weird interdependencies over different hooks and all stuff is fragile wrt small changes. This should fix PR8749 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@122155 91177308-0d34-0410-b5e6-96231b3b80d8
