I have no idea what's going on here. This code was moved around/introduced in change cb26b01d57f5 and starts crashing with a NULL dereference once I apply https://reviews.llvm.org/D123090. I assume that I've unwittingly taught the attributor enough that it's able to do more clever things than in the past, and it's able to trip on this case. I make no claims about the correctness of this patch, but it passes tests and seems to fix all the crashes I've been seeing. Differential Revision: https://reviews.llvm.org/D129589
