///   1. Check that all integer arguments and return values less than 64 bits
///      are sign/zero extended.
///   2. Check that all complex arguments and return values are placed in
///      registers if it is possible.  Not treat it as aggregate.
///   3. Check that a function declared without argument type declarations is
///      treated as VARARGS (in order to place arguments in both registers and
///      memory locations in the back end)
