add a test that non_overlapping checks dont generate too many guards (#120106)
Pre-emptive test in OSS to ensure that models relying on the "non-overlapping guards" checks do not suffer drastically w.r.t. guard slowness. Current plan is to follow up on this with a "real" fix, to generate a linear number of these guards.
