      Revert of X87: Reimplement Maps and Sets in JS (patchset #1 id:1 of https://codereview.chromium.org/1066373002/)

Reason for revert:
Reverting as it resulted in a closed waterfall.

Original issue's description:
> X87: Reimplement Maps and Sets in JS
>
> port 909500aa (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:

>       %_JSCollectionGetTable
>       %_StringGetRawHashField

      port 909500aa (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).
