State-Changed-Why:
    It is dealing with SSE registers.  Looks like 7630 duplicate.  We allow DImode in XMM and subreg DI->DF is actually the problem - we fail to reload DImode value to DFmode that is quite correct.  Perhaps CLASS_CANNOT_CHANGE_MODE for FLOAT_REGS?
    I've raised the priority of the other bug, so I am keeping this medium
