Fix leak of edge vector in IPA CP

Browse Source 
The following makes gather_edges_for_value return an auto_vec,
simplifying the single caller decide_about_value and fixing the
leak of the callers vector upon early return.

	* ipa-cp.cc (gather_edges_for_value): Return an auto_vec.
	(decide_about_value): Simplify, fixing leak of callers.
