This is a pretty straight forward translation for COFF, we just need to stick the data in a COMDAT section marked as IMAGE_COMDAT_SELECT_NODUPLICATES. N.B. We must be careful to avoid sticking entities with private linkage in COMDAT groups. COFF is pretty hostile to the renaming of entities so we must be careful to disallow GlobalVariables with unstable names. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@204703 91177308-0d34-0410-b5e6-96231b3b80d8
