I patched this in and verified it works. Clang makes a separate funclet for the lifetime end, which is suboptimal, but LLVM knows how to simplify it down to one. The stack coloring optimization in the backend doesn't fire yet, though. =/

Can you add a simple test for this? Make something similar to test/CodeGenCXX/microsoft-abi-eh-cleanups.cpp but with optimizations enabled.
