[BUGFIX PATCH 0/4] perf probe: Fixes bugs in show-lines and show vars etc.

[Masami Hiramatsu]

Hi Arnaldo,

Here are some more patches for fixing bugs which I found
while testing it.

 - [1/4]: I found that the debuginfo had precise line information
	but including non-statement and end-of-sequence entries.
	Those must be ignored because not represent target line.

 - [2/4]: I also found that there is GNU_call_site DIEs in debuginfo,
	which represents the location which calls another function.
	Since it is not an instance of inlined function, it must be
	ignored while searching instances of inlined function.

 - [3/4]: However, while listing up the available lines, we also need
	to show the lines calling another function. So if call_line and
	call_file attribute are same as line information, it shows that
	line as available.

 - [4/4]: It's a small fix to skip overlapped location while showing
	available variables.


Thank you,
