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

  # and 1 frames (use `bt' command for all frames)

        from <internal:numeric>:257:in 'Integer#times'
        from rescue-test.rb:1:in '<main>'
```

This is because `rb_debug_inspector_backtrace_locations` returned a
modified backtrace, which skips rescue/ensure frames, but
`rb_debug_inspector_frame_XXX_get`'s index is considered for a raw
backtrace, which includes rescue/ensure frames.

The problem wil be fixed by ruby/ruby#13510.
However, now the backtrace includes rescue/ensure frames, so some tests
in debug gem fails. This fixes the test failures.
