ThinLTOBitcodeWriter: Do not follow operand edges of type GlobalValue when looking for virtual functions. Such edges may otherwise result in infinite recursion if a pointer to a vtable is reachable from the vtable itself. This can happen in practice if a TU defines the ABI types used to implement RTTI, and is itself compiled with RTTI. Fixes PR32121. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@296839 91177308-0d34-0410-b5e6-96231b3b80d8
