Summary: The current default of appending "_"+entry block label to the new extracted cold function breaks demangling. Change the deliminator from "_" to "." to enable demangling. Because the header block label will be empty for release compile code, use "extracted" after the "." when the label is empty. Additionally, add a mechanism for the client to pass in an alternate suffix applied after the ".", and have the hot cold split pass use "cold."+Count, where the Count is currently 1 but can be used to uniquely number multiple cold functions split out from the same function with D53588.
