    amdgcn: fix vec_ucmp infinite recursion
    
    I suppose this pattern doesn't get used much! The unsigned compare was 
meant to
    be defined using the signed compare pattern, but actually ended up trying to
    recursively call itself.  This patch fixes the issue in the obvious way.
    
    gcc/ChangeLog:
    
            * config/gcn/gcn-valu.md (vec_cmpu<mode>di_exec): Call gen_vec_cmp*,
            not gen_vec_cmpu*.
