Log:
Remove an unnecessary workaround introduced in r259975. (NFC)
Now that LLVM r259973 allows replacing a temporary type with another
temporary we can rely on the original implementation.
It is possible for enums to be created as part of
their own declcontext. In this case a FwdDecl will be created
twice. This doesn't cause a problem because both FwdDecls are
entered into the ReplaceMap: finalize() will replace the first
FwdDecl with the second and then replace the second with
complete type.
Thanks to echristo for pointing this out.
