Summary: They are returned indirectly which causes the other arguments to move to the next argument slot. With this, utils/ABITest does not discover any failing cases in the first 500 attempts on big/little endian for O32. Previously some of these failed. Also tested N32/N64 little endian (big endian has other known issues) with no issues.
