  -----------
  [llvm-readobj] - Fix crashes and misbehaviors when reading strings from broken string tables.

There are cases when we either might print garbage or crash when
reading strings for dumping dynamic tags.

For example when a string table is not null-terminated or goes past the EOF.
This patch fixes issues mentioned.
