rs6000: Fix constraint v with rs6000_constraints[RS6000_CONSTRAINT_v] 

Currently we hardcode ALTIVEC_REGS for register constraint v and
RS6000_CONSTRAINT_v looks confusing, this is to fix it with
rs6000_constraints[RS6000_CONSTRAINT_v] to align with some other
existing register constraints with RS6000_CONSTRAINT_*.

gcc/ChangeLog:

	* config/rs6000/constraints.md (register constraint v): Use
	rs6000_constraints[RS6000_CONSTRAINT_v] instead of ALTIVEC_REGS.
