[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.
