[PATCH] rs6000: Fix constraint v with rs6000_constraints[RS6000_CONSTRAINT_v]

[Kewen.Lin via Gcc-patches]

Hi,

This patch is to fix register constraint v with
rs6000_constraints[RS6000_CONSTRAINT_v] instead of ALTIVEC_REGS,
just like some other existing register constraints with
RS6000_CONSTRAINT_*.

I happened to see this and hope it's not intentional and just
got neglected. 

Bootstrapped and regtested on powerpc64le-linux-gnu P9 and
powerpc64-linux-gnu P8.

Is it ok for trunk?

BR,
Kewen
