----------------
I think the analyzer core should do this. This code already has a global effect on the analysis - it's enough for one checker to generate the sink. Additionally, there's also the CFG-based variant of suppress-on-sink, which would need to be extended to support this as well - this other variant kicks in when the analysis was interrupted before reaching the sink (see D35673 and D35674).
