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.
