Hi.
Following small series makes deduplication of predictors in following 2 ways:
1) remove duplicate prediction that is guessed with the same probability
(different than 1/2) to both edges
2) remove duplicates for a prediction that belongs with the same probability
to a single edge
Patch also changes dump output format a bit, thus analyze_brprob.py script
has been also modified to understand the format.
Bootstrapped and regtested on x86_64-linux
Ready for trunk?

Introduce filtering for edge_predictions.
Add edge predictions pruning
