return auto_vec from get_loop_hot_path
This ensures callers take ownership of the returned vector.
Signed-off-by: Trevor Saunders <tbsaunde@tbsaunde.org>
gcc/ChangeLog:
* cfgloop.h (get_loop_hot_path): Return auto_vec<basic_block>.
* cfgloopanal.c (get_loop_hot_path): Likewise.
* tree-ssa-loop-ivcanon.c (tree_estimate_loop_size): Likewise.
