This is the final patch for DPVAssign support, implementing the actual creation of DPVAssigns and allowing them to be converted along with dbg.values and dbg.declares. Numerous tests landed in previous patches will no longer be rotten after this patch lands (previously they would trivially pass due to DPVAssigns not actually being used), and a further batch of tests have been added here that require the changes in this patch before they pass.
