MIPS: Add MIN/MAX.fmt instructions support for MIPS R6

This patch adds the smin/smax RTL mode for the
min/max.fmt instructions.

Also, since the min/max.fmt instrucions applies to the
IEEE 754-2008 "minNum" and "maxNum" operations, this
patch also provides the new "fmin<mode>3" and
"fmax<mode>3" modes.

gcc/ChangeLog:

	* config/mips/i6400.md (i6400_fpu_minmax): New
	define_insn_reservation.
	* config/mips/mips.h (ISA_HAS_FMIN_FMAX): Define new macro.
	* config/mips/mips.md (UNSPEC_FMIN): New unspec.
	(UNSPEC_FMAX): Same as above.
	(type): Add fminmax.
	(smin<mode>3): Generates MIN.fmt instructions.
	(smax<mode>3): Generates MAX.fmt instructions.
	(fmin<mode>3): Generates MIN.fmt instructions.
	(fmax<mode>3): Generates MAX.fmt instructions.
	* config/mips/p6600.md (p6600_fpu_fabs): Include fminmax
	type.

gcc/testsuite/ChangeLog:

	* gcc.target/mips/mips-minmax1.c: New test for MIPS R6.
	* gcc.target/mips/mips-minmax2.c: Same as above.
