    /*
     * Generic 32-bit "lit8" binary operation.  Provide an "instr" line
     * that specifies an instruction that performs "result = w0 op w1".
     * This could be an ARM instruction or a function call.  (If the result
     * comes back in a register other than w0, you can override "result".)
     *
     * If "chkzero" is set to 1, we perform a divide-by-zero check on
     * vCC (w1).  Useful for integer division and modulus.
     *
     * For: add-int/lit8, rsub-int/lit8, mul-int/lit8, div-int/lit8,
     *      rem-int/lit8, and-int/lit8, or-int/lit8, xor-int/lit8,
     *      shl-int/lit8, shr-int/lit8, ushr-int/lit8
