It takes some time to look for inline stack for callgraph addresses. So it provides new options "--inline-line" and "--inline-name" to let user decide if enable this feature.
--inline-name: If a callgraph address belongs to an inlined function, the inline stack will be printed. Each entry is the inline function name. --inline-line: If a callgraph address belongs to an inlined function, the inline stack will be printed. Each entry is the inline function source line.
