Pavel Vlasov	349d5ba012	--perf_instrument parameter now has int type and 0, 1, 2 modes (1 - simple trees, 2 - expanded trees for functions with same name but different calling address); Maximum depth limit var was added to the instrumentation structure; Trace names output console output fix: improper tree formatting could happen; Output in case of error was added; Custom regions improvements; Improved timing and weight calculation for parallel regions; New TC (threads counter) value to indicate how many different threads accessed particular node; parallel_for, warnings fixes and ReturnAddress code from Alexander Alekhin;	8 years ago
