global absolute probability analysis:
* added switch probability, changed branch probability from int to double
* absolute probability on each FixedNode computed by new ComputeProbabilityPhase

* added GraalOptions.ProbabilityAnalysis flag: builds probability information and let inlining and escape analysis use it
