The debug gem can abort when stepping into a rescue clause:
```
$ ruby -Ilib exe/rdbg rescue-test.rb
[1, 7] in rescue-test.rb
=> 1| 1.times do
2| begin
3| raise
4| rescue
5| p 1
6| end
7| end
=>#0 <main> at rescue-test.rb:1
(rdbg) s # step command
[1, 7] in rescue-test.rb
1| 1.times do
2| begin
=> 3| raise
4| rescue
5| p 1
6| end
7| end
=>#0 block in <main> at rescue-test.rb:3

This is caused by the design issue of the debug inspector API.
See ruby/ruby#13508
This changeset fixes the issue by using a newly-introduced debug
inspector API, namely `rb_debug_inspector_frame_loc_get`.

There was a problem hiding this comment.
Ruby spoofs the location of the C frame to the location of the caller. But rb_debug_inspector_frame_loc_get does not do this spoofing, so the location of Process#kill is not sigint-test.rb:2 but #<none>:0.
$ ruby -Ilib exe/rdbg sigint-test.rb
[1, 3] in sigint-test.rb
=> 1| trap('SIGINT'){ puts "SIGINT" }
2| Process.kill('SIGINT', Process.pid)
3| p :ok
=>#0 <main> at sigint-test.rb:1
(rdbg) c # continue command
# No sourcefile available for
=>#0 [C] Process.kill at #<none>:0
#1 <main> at sigint-test.rb:2
Stop by SIGINT
#<Proc:0x00007950068cd4b0 sigint-test.rb:1> is registered as SIGINT handler.
`sigint` command execute it.
(rdbg)
This change reflects that.
