This reverts commit r208934. The patch depends on aliases to GEPs with non zero offsets. That is not supported and fairly broken. The good news is that GlobalAlias is being redesigned and will have support for offsets, so this patch should be a nice match for it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@208978 91177308-0d34-0410-b5e6-96231b3b80d8
