----------------
It appears that here we check only fn attributes for Callee, but I think it's also possible for a CS can have its own attributes. Shouldn't we check CS.hasFnAttr(Attribute::Cold) or CS.hasFnAttr(Attribute::InlineHint) as well?  E.g., a Callee itself is not Cold, but a CS to the Callee is Cold. If yes, may be a separate patch.
