  Log Message:
  -----------
  [PGO] Don't unconditionally request BBInfo in verifyFuncBFI() (#140804)

This breaks in the case where there are unreachable blocks after an
entry block with no successors, which don't have a `BBInfo`, causing
crashes.

`BBInfo` doesn't exist for unreachable blocks, see
https://reviews.llvm.org/D27280.

Fixes #135828.
