Fix NullCheck register modeling

NullCheck is currently tagged with `isLocalDefUse` on all targets. However, for XARCH it is implemented with a compare (no target), and for ARM64 it is implemented with a load to REG_ZR, so neither of those require a target register.
Only on ARM is a target register required, and it is a localDefUse because the result is not used.
