mips.md (any_shift): New code macro.

	* config/mips/mips.md (any_shift): New code macro.
	(optab, insn): New code attributes.
	({ashl,ashr,lshr}[sd]i3): Redefine using :GPR and any_shift.
	Use the standard rather than internal patterns for the MIPS16
	double-shift optimization.
	(*{ashl,ashr,lshr}[sd]i3): New names for the non-mips16 shift patterns.
	Redefine using :GPR and any_shift.
	(*{ashl,ashr,lshr}si3_extend): Generalize ashlsi3_internal1_extend
	to cover all three shifts.
	(*{ashl,ashr,lshr}si3_mips16): New names for the mips16 SImode shifts.
	Redefine using any_shift.  Use :GPR and any_shift to combine splitters.
	(*{ashl,ashr,lshr}di3_mips16): New names for the mips16 DImode shifts.
