Fix div[u]2.
Previous code assummed 32 by 32 bit divmod operation, and survived
x86_64 test only by sheer luck. MIPS wasn't so forgiving.
Are you sure it is needed ? div[u]2 support in currently optional in TCG. On some hosts such as PowerPC, implementing div[u] directly is simpler. rem[u] can be implemented generically then.
