* predict.c (probability_reliable_p): New predicate.
(edge_probability_reliable_p, br_prob_note_reliable_p): Likewise.
(predict_loops): Do not predict loop exit with less than 2%
probability.
* basic-block.h (edge_probability_reliable_p,
br_prob_note_reliable_p): Declare.
* ia64.h (ia64_print_operand): Do not disable on-chip branch
prediction when static predictor is not reliable.
* rs6000.c (output_cbranch): Likewise.
