CC_RSBmode should be used where the comparison is set by an RSB immediate,

be (COMPARE (not (reg)) (~const)).
CC_Bmode should be used if only the C flag is correct after a subtract
(eg after an unsigned borrow with carry-in propagation).
(used for DImode signed comparisons).
CC_ADCmode is used when the carry is formed from the output of ADC for an
addtion. In this case we cannot use the trick of comparing the sum
against one of the other operands.
CCmode should be used otherwise. */
