 * Resolved argument types for the AML Interpreter

 *
 * Note1: These values are completely independent from the ACPI_TYPEs
 *        i.e., ARGI_INTEGER != ACPI_TYPE_INTEGER
 *
 * Note2: If and when 5 bits becomes insufficient, it would probably be best
 * to convert to a 6-byte array of argument types, allowing 8 bits per argument.
