For this one I have to increment the `Index` by one if it is a member call. Either at the creation of the region or at getting the type. However, after an hour of research I found no way to determine this for operator calls. An operator call is `CXXOperatorCallExpr` without a method that tells whether it is a member or a non-member operator. This is a problem because `ParmVarDecl::getFunctionScopeIndex()` returns the real index, but `CallExpr::getArg()` takes the "raw" index, where `0` means the implicit `this` argument for member calls.
