COMDATs must be identically named to the symbol. When support for COMDATs was introduced, the symbol rewriter was not updated, resulting in rewriting failing for symbols which were placed into COMDATs. This corrects the behaviour and adds test cases for this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@227261 91177308-0d34-0410-b5e6-96231b3b80d8
