Thanks for the patch!

Agreed. If the `@llvm.objectsize` call points directly to the `alloca` we're trying to kill, then I think it should be trivial to evaluate on the spot. This way, we can go ahead and eliminate the `alloca` instead of hoping that InstCombine runs again to get rid of it for us. :)
