  Log Message:
  -----------
  [llvm-readobj] - Do not crash when SHT_HASH table is broken.

We have scenarios when the logic of --elf-hash-histogram/--hash-symbols/--hash-table
options might crash when given a broken hash table.

This patch adds pre-checks for tables for these 3 options
and provides test cases.
