Subject: [PATCH v3 3/5] perf report: Create new inline options

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.
