This change correctly sets the attributes on the callsites generated in thunks. This makes sure things such as sret, sext, etc. are correctly set, so that the call can be a proper tailcall. Also, the transfer of attributes in the replaceDirectCallers function appears to be unnecessary, but until this is confirmed it will remain.
