* predict.c (drop_profile): New function.
(handle_missing_profiles): Ditto.
(counts_to_freqs): Don't overwrite estimated frequencies
when function has no profile counts.
* predict.h (handle_missing_profiles): Declare.
* tree-inline.c (freqs_to_counts): New function.
(copy_cfg_body): Invoke freqs_to_counts as needed.
* tree-profile.c (tree_profiling): Invoke handle_missing_profiles.
