mips.md: Use move_operand in splitters for 64-bit moves.

	* config/mips/mips.md: Use move_operand in splitters for 64-bit moves.
	(movdi, movsi, movhi, movqi, movsf, movdf): Remove predicates.
	(*movdi_32bit_mips16, *movsi_mips16, *movhi_mips16, *movqi_mips16)
	(*movsf_mips16, *movdf_mips16):  Name unnamed patterns.  Use
	move_operand as source predicate in all cases.
	(*movdi_32bit): Renamed from movdi_internal.  Remove 'F' constraint.
	Test reg_or_0_operand.  Use move_operand as source predicate.
	(*movdi_64bit): Renamed from movdi_internal2.  Test reg_or_0_operand.
	(*movdi_64bit_mips16): Renamed from movdi_internal2_mips16.
	(*movsi_internal): Renamed from movsi_internal.  Test reg_or_0_operand.
	(movhi, movqi, movsf, movdf): Use mips_legitimize_move.
	(*movhi_internal): Renamed from movhi_internal.  Test reg_or_0_operand.
	Use move_operand as source predicate.  Remove 'K' constraint.
	(*movqi_internal): Likewise movqi_internal.
	(*movsf_hardfloat): Renamed from movsf_internal1.  Test
	reg_or_0_operand.  Use move_operand as source predicate.
	(*movsf_softfloat): Likewise movsf_internal2.
	(*movdf_hardfloat_64bit): Likewise movsf_internal1a.
	(*movdf_hardfloat_32bit): Likewise movsf_internal1b.
	(*movdf_softfloat): Likewise movdf_internal2.
	* config/mips/mips.c (move_operand): Match arbitrary CONST_INTs
	for DImode if !TARGET_64BIT.
	(mips_legitimize_move): Simplify accordingly.
