Georgii Rymar 58bb0e630a [llvm-symbolizer] - Fix the crash in GNU output style with --no-inlines and missing input file.
Fixes https://bugs.llvm.org/show_bug.cgi?id=48882.

If the input file does not exist (or has a reading error), the
following code will crash if there are two or more input addresses.

```
auto ResOrErr = Symbolizer.symbolizeInlinedCode(
  ModuleName, {Offset, object::SectionedAddress::UndefSection});
Printer << (error(ResOrErr) ? DILineInfo() : ResOrErr.get().getFrame(0));
```

For the first address, `symbolizeInlinedCode` returns an error.
For the second address, `symbolizeInlinedCode` returns an empty result
(not an error) and `.getFrame(0)` will crash.

This test checks that when inlined frames are not shown (--no-inlines) and the output
style is set to GNU (--output-style=GNU) the name of an inlined function is not
replaced with the name of the top caller function. At the same time, the current
behavior of llvm-symbolizer is preserved with --output-style=LLVM or when
the option is not specified.
