Vedant Kumar bd94b4287c [HotColdSplit] Do not split out `resume` instructions 
Resumes that are not reachable from a cleanup landing pad are considered
to be unreachable. It’s not safe to split them out.

Vedant Kumar 32a014d048 [HotColdSplit] Simplify tests by lowering their splitting thresholds 
This gets rid of the brittle/mysterious calls to @sink()/@sideeffect()
peppered throughout the test cases. They are no longer needed to force
splitting to occur.

Vedant Kumar 09415a850e [CodeExtractor] Do not marked outlined calls which may resume EH as noreturn 
Treat terminators which resume exception propagation as returning instructions
(at least, for the purposes of marking outlined functions `noreturn`). This is
to avoid inserting traps after calls to outlined functions which unwind.
