[PATCH] D13774: [CodeGen] Mark setjmp/catchret MBBs address-taken

[Reid Kleckner via llvm-commits]

rnk added a comment.

I'd actually like this transform to work, and I don't want WinEH to get entangled with BlockAddress support, which is what hasAddressTaken is for.

My idea was to create a pseudo instr during frame lowering that defs EAX/RAX and takes no operands. During X86MCInstrLowering, we would scan forwards to the CATCHRET terminator, get the destination MBB operand, and print its symbol.
