This helps to avoid unnecessary IS_REFERENCE checks. This changes some notices "Only variables should be passed by reference" to exception "Cannot pass parameter %d by reference". Also, for consistency, compile-time fatal error "Only variables can be passed by reference" was converted to exception "Cannot pass parameter %d by reference"
