At the beginning of run, initialize analyis info availability for _ALL_
pass managers. Otherwise, stale available analysis info, from the managers not yet run, may cause pass manager to take wrong turn. This fixes CBE test failures reported by nightly tester. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@32726 91177308-0d34-0410-b5e6-96231b3b80d8
