  |     [PATCH] [AutoFDO/devirt] Fix ICE with duplicate speculative ID
  |     
  |     This happens due to autoprofile pass makes edge make_speculative.
  |     Then ipa-devirt does the same with the same speculative_id which
  |     reults in duplicate speculative_id and ICE.
  | ... 31 lines of the commit log omitted.
