[cfe-dev] FunctionDecls by typedef crash the C++ front-end

typedef void fn(int);
fn f;

There are no ParmVarDecls created for the 'f' FunctionDecl, and I assume 
this is intended to save space.
This crashes the C++ front-end when trying to use the ParmVarDecls 
(mostly for handling default args).

In C there is no problem since ParmVarDecls are used only for 
definitions, otherwise FunctionTypeProto is used
