re PR target/69667 (ppc64le -mlra: ICE: Max. number of generated reload insns per insn is achieved (90))

[gcc]
2016-02-04  Michael Meissner  <meissner@linux.vnet.ibm.com>

	PR target/69667
	* config/rs6000/rs6000.md (mov<mode>_64bit_dm): Use 'd' constraint
	instead of 'ws', and 'wh' instead of 'wm' since TFmode/IFmode are
	not allowed into the traditional Altivec registers.
	(movtd_64bit_nodm): Likewise.
	(mov<mode>_32bit, FMOVE128_FPR iterator): Likewise.
