I think it's the right thing to do to get the bot back into the green state today. I leave the long-term decision and the question if 64 is enough for everybody to people more familiar with the vector lowering code.

As for the patch I think you should add an assert(i < sizeof(NonZeros) * 8) in front of the shift so that this error can be easily reproduced without the need to do an asan or ubsan build.
