With msvc I get
unresolved external symbol llvm_profile_instrument_target 
referenced in function _D4hash7keynode9xtoHashFNbNeKxSQBfQBdZm
unresolved external symbol llvm_profile_runtime referenced in 
function llvm_profile_runtime_user

And with link-internally I get
lld-link: error: undefined symbol: llvm_profile_runtime
lld-link: error: undefined symbol: llvm_profile_instrument_target
