	* config/rs6000/predicates.md (easy_fp_constant): Delete redunant
	tests for 0.0.

	* config/rs6000/vector.md (VEC_R): Move secondary reload support
	insns to rs6000.md from vector.md.
	(reload_<VEC_R:mode>_<P:mptrsize>_store): Likewise.
	(reload_<VEC_R:mode>_<P:mptrsize>_load): Likewise.
	(vec_reload_and_plus_<mptrsize>): Likewise.

	* config/rs6000/rs6000.md (Fa): New mode attribute to give
	constraint for the Altivec registers for a type.
	(RELOAD): New mode iterator for all of the types that have
	secondary reload address support to load up a base register.
	(extendsfdf2_fpr): Use correct constraint.
	(copysign<mode>3_fcpsgn): For SFmode, use correct xscpsgndp
	instruction.
	(floatsi<mode>2_lfiwax): Add support for -mupper-regs-{sf,df}.
	Generate the non-VSX instruction if all registers were FPRs.  Do
	not use the patterns in vsx.md for scalar operations.

	it more obvious that the code is for pre-ISA 2.06 machines.
	(floatdisf2_internal2): Likewise.
	(floatunsdisf2_fcfidus): Add support for -mupper-regs-{sf,df}.
	Generate the non-VSX instruction if all registers were FPRs.  Do
	not use the patterns in vsx.md for scalar operations.
	(floatunsdisf2_mem): Likewise.
	(reload_<RELOAD:mode>_<P:mptrsize>_store): Move the reload
	handlers here from vector.md, and expand the types we generate
	reload handlers for.
	(reload_<RELOAD:mode>_<P:mptrsize>_load): Likewise.
	(vec_reload_and_plus_<mptrsize>): Likewise.

	* config/rs6000/vsx.md (vsx_float<VSi><mode>2): Only provide the
	vector forms of the instructions.  Move VSX scalar forms to
	rs6000.md, and add support for -mupper-regs-sf.
