Use move-aware auto_vec in map

Using auto_vec rather than vec for means the vectors are release
automatically upon return, to stop the leak. The problem seems is that
auto_vec<T, N> is not really move-aware, only the <T, 0> specialization
is.

gcc/ChangeLog:

	* tree-profile.cc (find_conditions): Use auto_vec without
	embedded storage.
