	* config/bfin/bfin.md (<optab>di3): Now a define_expand which expands
	logical operations piecewise.
	(<optab>di_zesidi_di, <optab>di_sesidi_di, negdi2, one_cmpldi2,
	zero_extendsidi2, subdi_di_zesidi, subdi_zesidi_di, subdi_di_sesidi,
	subdi_sesidi_di): Delete.
	(add_with_carry): Produce carry in CC instead of a DREG to shorten
	the generated sequence.  Allow three-reg add in constraints.  Rewrite
	the rtl expression for carry to avoid zero_extend of a constant.
	(sub_with_carry): New pattern.
	(adddi3, subdi3): Change into define_expand.  For subtract, generate a
	different sequence not involving jumps.
	(notbi): Now a named pattern.
