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*.
