+ * frame.c (frame_stash_add): Now returns whether a frame with the
+ same ID was already known.
+ (compute_frame_id): New function, factored out from get_frame_id.

+ (get_prev_frame_if_no_cycle): New function. Detects wider stack
+ cycles.
+ (get_prev_frame_1): Use it instead of get_prev_frame_raw directly,
+ and checking for stack cycles here.
