Introduce PROB_UNINITIALIZED constant and use it in predict.def.
2018-01-19 Martin Liska <mliska@suse.cz>
* predict.c (predict_insn_def): Add new assert.
(struct branch_predictor): Change type to signed integer.
(test_prediction_value_range): Amend test to cover
PROB_UNINITIALIZED.
* predict.def (PRED_LOOP_ITERATIONS): Use the new constant.
(PRED_LOOP_ITERATIONS_GUESSED): Likewise.
(PRED_LOOP_ITERATIONS_MAX): Likewise.
(PRED_LOOP_IV_COMPARE): Likewise.
* predict.h (PROB_UNINITIALIZED): Define new constant.
