Original issue's description:
> X87: Reimplement Maps and Sets in JS
>
> port 909500aa1db9789b68e101045a6359a7fcb30e83 (r27605)
>
> original commit message:
>     Previously, the only optimized code path for Maps and Sets was for String keys.
>     This was achieved through an implementation of various complex operations
>     in Hydrogen. This approach was neither scalable nor forward-compatible.
>
>     This patch adds the necessary intrinsics to implement Maps and Sets almost entirely
>     in JS. The added intrinsics are:
>
>       %_FixedArrayGet
>       %_FixedArraySet
>       %_TheHole
>       %_JSCollectionGetTable
>       %_StringGetRawHashField
>
>     With these additions, as well as a few changes to what's exposed as runtime functions,
>     most of the C++ code backing Maps and Sets is gone (including both runtime code in
>     objects.cc and Crankshaft in hydrogen.cc).
