Found in a bootstrap of LLVM with implicit modules, resulting in a deadlock of some Orc unit tests with libstdc++ 8.1. An enum was used as part of the implementation of std::recursive_mutex and this bug resulted in the constant initialization of zero instead of the desired non-zero value. => Badness. Richard Smith tells me neither of these fields are necessarily canonical & so using declaresSamEntity is the right solution here (rather than changing both of these Fields to be canonical by construction/from their source) llvm-svn: 361428
