[BUGFIX PATCH 0/3] perf/probe: Fix available line bugs

[Masami Hiramatsu]

Hi,

Here are some bugfixes related to showing available line (--line/-L)
option. I found that gcc generated some subprogram DIE with only
range attribute but no entry_pc or low_pc attributes.
In that case, perf probe failed to show the available lines in that
subprogram (function). To fix that, I introduced some bugfixes to
handle such cases correctly.

Thank you,
