#3970 — 9.4.2.3, 19.1.3.6, 24.3.1.1, 24.3.2, 24.3.2.1: Missing ReturnIfAbrupt after IsArray


9.4.2.3 ArraySpeciesCreate(originalArray, length) Abstract Operation
- step 4

19.1.3.6 Object.prototype.toString ( )
- step 4

24.3.1.1 Runtime Semantics: Walk Abstract Operation
- step 3.a

24.3.2 JSON.stringify ( value [ , replacer [ , space ] ] )
- step 4.b

24.3.2.1 Runtime Semantics: Str Abstract Operation
- step 11.a

IsArray is fallible, so it needs be guarded with a ReturnIfAbrupt call.
