[PATCH] D18046: [X86] Providing correct unwind info in function epilogue

Hi Keno, thanks for commenting. As for the splitting of the epilogue over two MBBs, I have come across a case where 'pop' instructions were separated from the 'ret' instruction ('pop' instrs were in one MBB, and 'ret' was in another MBB). That case would be covered with the proposed solution. I haven't come across a case where 'add', 'pop' instructions that form an epilogue are split over multiple MBBs.
