Log:
	* config/mips/mips.md (GPR2): New mode iterator.
	(seq): Add comment.
	(*seq_<mode>, *seq_<mode>_mips16, *sne_<mode>, *sgt<u>_<mode>,
	*sgt<u>_<mode>_mips16, *sge<u>_<mode>, *slt<u>_<mode>,
	*slt<u>_<mode>_mips16 *sle<u>_<mode>, *sle<u>_<mode>_mips16):
	Rewrite these to take two modes, the mode of comparison and the
	mode of the destination.
	* config/mips/mips.c (mips_expand_scc): Instead of having
	paradoxical subreg as destination, expand "narrowing" scc if mode
	of comparison is SI and target is requested in DI mode.
	(mips_emit_int_order_test): Update comment.  Make mode of
	comparison match CMP0 rather than TARGET.  When creating inverse
	target use mode of TARGET.
