Answering my own question with this: I managed to completely overlook the fact
that DWARF (since at least v3) has supported fields within the line program state
machine that explicitly record whether a particular entry indicates a prologue end
(DW_LNS_set_prologue_end) and epilogue begin (DW_LNS_set_epilogue_begin).
