State-Changed-Why:
    The ARM back-end was playing a trick when using the special
    output rule '%d<op>' where NULL meant don't put out anything.
    
    This was causing the verbose-asm code to get upset -- it expected
    an operand it could dereference.  So pass const_true_rtx in
    those cases when we want the condition to be 'always'.  For the 
    '%D<op>' case abort if passed const_true_rtx, since that means
    'not always' (ie never), and we shouldn't be generating such
    instructions.
