Please also add a new version number for this (where the feature is only supported for this version and up) like the other features: https://github.com/llvm/llvm-project/blob/main/llvm/lib/Object/ELF.cpp#L850-854.

Thanks. We have split the original PR into two separate ones. The current PR only contains modifications related to ELF and basic block hash calculation. Additionally, we have updated the version number of SHT_LLVM_BB_ADDR_MAP.
