My argument is that the user is capable of passing something like `-Xarch_host -fsanitize=undefined -Xarch_device -fsanitize=address` if they want fine-grained control, or don't want it on the CPU but want it on the CPU and vice-versa. This patch adds `-fanitize-gpu` which is a completely separate option that only works in this single case.

I agree, -fsanitize=address is supposed to enable instrumentation on both host and device...and that is exactly what happens now.  If this patch is affecting the existing behavior then something is wrong.
