New issue 4175 by erik.corry: JSON.parse of small object with element keys is too afraid of dictionary mode
https://code.google.com/p/v8/issues/detail?id=4175

echo "%HasDictionaryElements(JSON.parse('{\"0\":0, \"1040\":1040}'))" | ./out/x64.release/d8 --allow-natives-syntax

Prints false ie this object is not a compact dictionary mode object, but an 8kbyte flat object.

The boundary is 1041, strangely.

Toon is currently revising elments (numberic keys) handling in V8, so this is blocked on that work.
