To link together instructions in a rpt group we currently (ab)use list_head. This is a bit of a hack because we don't actually have a list_head that points to the first instruction without being embedded in an instruction itself (the way list_head is supposed to be used). Instead, the list_head embedded in the first instruction of a rpt group also serves as the one pointing to the list. In order make a distinction between the first and last instruction (for which the main list_head would usually be used), we rely on the fact that (currently) instructions in a rpt group are emitted in order which means that later instructions have a larger serialno than earlier ones. In order to make all this less hacky, and to lift the restriction of needing instructions to be emitted in order, replace the list_head with explicit rpt_next/rpt_prev pointers which link the instructions together in a doubly but non-circular linked list.
