[PATCH v4 3/5] perf report: Create new inline option

[Jin Yao]

It takes some time to look for inline stack for callgraph addresses.
So it provides new option "--inline" to let user decide if enable
this feature.

--inline:
If a callgraph address belongs to an inlined function, the inline stack
will be printed. Each entry is the inline function name.
