  Log Message:
  -----------
  [SHT_LLVM_BB_ADDR_MAP] Emit callsite offsets in the `SHT_LLVM_BB_ADDR_MAP` section. (#146563)

Callsite offsets will help map addresses to the right position in the
basic block (before or after a callsite).

This PR also bumps the BBAddrMap version to 3.

The encoding/decoding ability is already pushed upstream
8d7a8fcc3ab9f6d4c4a7e4312876fe94ed3d6c4f.
