We now have

t:
        cmpwi 7,4,0
        beqlr- 7
        li 0,0
        dst 3,0,0
        blr

but the `prefetch' case is not solved yet.

Changing `prefetch' to take a memory_operand instead
of an address_operand would do the trick, I think.
This needs to be changed in generic code too, then.

This makes me think this also shows on other platforms?
