We currently bail out of global localization if the global has non-instruction users. However, often these can be simple bitcasts or constant-GEPs, which we can easily turn into instructions before localizing. Be a bit more aggressive. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@253584 91177308-0d34-0410-b5e6-96231b3b80d8
