ArraySet instructions can trigger a GC only when perforing a type
check. When clearing the needs type check flag, we should also
clear the CanTriggerGC flag from the instruction's side effects.
Note that once we clear the needs type check flag, we never set
it again.
Add check in graph checker that the needs type check and the can
trigger GC flag are consistent.
Add can_trigger_gc property to graph visualizer that reflects
whether the ArraySet instruction can trigger a GC.
