add move CTOR to auto_vec, use auto_vec for get_loop_exit_edges
This adds a move CTOR to auto_vec<T, 0> and makes use of a auto_vec<edge> return value for get_loop_exit_edges denoting that lifetime management of the vector is handed to the caller. The move CTOR prompted the hash_table change because it appearantly makes the copy CTOR implicitely deleted (good) and hash-table expansion of the odr_enum_map which is hash_map <nofree_string_hash, odr_enum> where odr_enum has an auto_vec<odr_enum_val, 0> member triggers this. Not sure if there's a latent bug there before this (I think we're not invoking DTORs, but we're invoking copy-CTORs). 2020-08-06 Richard Biener <rguenther@suse.de> * vec.h (auto_vec<T, 0>::auto_vec (auto_vec &&)): New move CTOR.
