	* config/rs6000/rs6000.md (f32_vsx): New mode attributes to
	refine the constraints used on 32/64-bit floating point moves.
	(f32_av): Likewise.
	(f64_vsx): Likewise.
	(f64_dm): Likewise.
	(f64_av): Likewise.
	(BOOL_REGS_OUTPUT): Use wt constraint for TImode instead of wa.
	(BOOL_REGS_OP1): Likewise.
	(BOOL_REGS_OP2): Likewise.
	(BOOL_REGS_UNARY): Likewise.
	(mov<mode>_hardfloat, SFmode/SDmode): Tighten down constraints for
	32/64-bit floating point moves.  Do not use wa, instead use ww/ws
	for moves involving VSX registers.  Do not use constraints that
	target VSX registers for decimal types.
	(mov<mode>_hardfloat32, DFmode/DDmode): Likewise.
	(mov<mode>_hardfloat64, DFmode/DDmode): Likewise.
