You'd hope not. I got this from the and-mask-sink.ll test in the same directory. Removing the profile-summary does indeed cause a crash, from the isFunctionHotINCallGraph call in CodeGenPrepare::_run which is odd.

It seems all tests in tests/Transform/CodeGenPrepare have the same profile-summary requirement.
