Eliminate excessive increment of deoptimization counters (e.g., with deep recursion of deoptimized function). Instead increment deoptimization_count for all (inlined) functions at deoptimization point if deoptimization was triggered from function's optimized code. Cases where that is not the case are OSR codes, lazy-deopts and code disabling due to loading/finalizing classes or guard invalidation.
Rename deoptimization_counter_threshold to max_deoptimization_counter_threshold.
