Exposes more constant globals that can be removed by the global optimizer. A specific example is the removal of the static global block address array in clang/test/CodeGen/indirect-goto.c. This change impacts only lower optimization levels. With LTO interprocedural const prop runs already before global opt. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@212284 91177308-0d34-0410-b5e6-96231b3b80d8
