Currently, parameters of functions without their definition present cannot be represented as regions because it would be difficult to ensure that the same declaration is used in every case. To overcome this, we introduce a new kind of region called `ParamRegion` which does not store the `Decl` of the parameter variable. Instead it stores the index of the parameter which enables retrieving the actual `Decl` every time using the function declaration of the stack frame.
