Passing a delegate as part of the parameter list for a second delegate causes UHT to crash on compile.

When declaring a delegate that takes another delegate as the variable type for one of its parameters, UHT will crash when attempting to compile the code.

1. Open UE4 Editor (any project)
2. Add code to project based on Actor (MyActor)
3. Copy the following into MyActor.h:

   DECLARE_DYNAMIC_DELEGATE_OneParam(FRegularDelegate, int32, SomeArgument);
   DECLARE_DYNAMIC_DELEGATE_OneParam(FDelegateWithDelegateParam, FRegularDelegate const &, RegularDelegate);
   

4. Compile

Result:
Unreal Header Generation Tool crashes shortly after the compile process starts.

Expected:
Declaring a delegate with another delegate as a parameter compiles and can be used.
