Same problem with ARM-specific EH. I ended with own information
scheme, where instructions are marked as "frame related" during all
prologue & epilogue emission and later are "recognized" during the MI
=> MCInst lowering. You might want to look into ARM backend, maybe we
can somehow "generalize" this approach.
