re PR target/63965 (ICE: in extract_constrain_insn, at recog.c:2230 on ppc64) 

2014-11-21  Michael Meissner  <meissner@linux.vnet.ibm.com>

	PR target/63965
	* config/rs6000/rs6000.c (rs6000_setup_reg_addr_masks): Do not set
	Altivec & -16 mask if the type is not valid for Altivec registers.
	(rs6000_secondary_reload_memory): Add support for ((reg + const) +
	reg) that occurs during push_reload processing.

	* config/rs6000/altivec.md (altivec_mov<mode>): Add instruction
	alternative for moving constant vectors which are easy altivec
	constants to GPRs.  Set the length attribute each of the
	alternatives.
