	PR target/59054
	* config/rs6000/rs6000.md (movdi_internal32): Eliminate
	constraints that would allow DImode into the traditional Altivec
	registers, but cause undesirable code generation when loading 0 as
	a constant.
	(movdi_internal64): Likewise.
	(cmp<mode>_fpr): Do not use %x for CR register output.
	(extendsfdf2_fpr): Fix constraints when -mallow-upper-df and
	-mallow-upper-sf debug switches are used.
