	Backport from mainline:
	gcc/
	2010-10-07  Tejas Belagod  <tejas.belagod@arm.com>
	* config/arm/neon.md (neon_unpack<US>_<mode>): Add 'w' to
	constraint, add register specifier in instruction template.
	(neon_vec_pack_trunc_<mode>): Likewise.
	(neon_vec_<US>mult_<mode>): Add register specifier to
	instruction template.
