LGTM! This seems fairly reasonable as a solution, all things considered. Have you been able to check whether this has any broad impacts on the quality of our codegen? My guess is that it doesn't since it seems that any code that would have had the vector elements simplified previously would have ended up in that infinite loop, but we went a long time without ever seeing that bug in the wild.
