[llvm-readelf/obj] - Improve error reporting when dumping group sections.

Authored by grimar on Thu, Nov 19, 7:31 AM.



Our code that dumps groups has 3 noticeable issues:

  1. It uses unwrapOrError in many places.
  2. It doesn't allow reporting unique warnings, because the getGroups helper is not a member of DumpStyle<ELFT>.
  3. It might just crash. See the comment for StrTableOrErr->data() + Sym.st_name line.

In this patch I am starting addressing these points.
For start I've converted one of unwrapOrError calls to a unique warning.
