+ The following code tries hard to be optimal. A general assumption
(which is true according to the data books I have) is that
2 * xchg is more expensive than pushl + movl + popl
(2 * movl is less expensive than pushl + popl).
Second unlike for the other registers we don't save the content of
- %ecx and %edx when we have than 1 and 2 registers resp.

The code below might look a bit long but we have to take care for
the pipelined processors (i586 and up). Here the `pushl' and `popl'
