Revert of [turbofan] Initial support for monomorphic/polymorphic property loads.

Revert of [turbofan] Initial support for monomorphic/polymorphic property loads. (patchset #3 id:100001 of https://codereview.chromium.org/1396333010/ )

Reason for revert:
Waterfall redness.

Original issue's description:
> [turbofan] Initial support for monomorphic/polymorphic property loads.
>
> Native context specialization now lowers monomorphic and
> polymorphic accesses to data and constant data properties on
> object and/or prototype chain. We don't deal with accessors
> yet, and we also completely ignore proxies (which is compatible
> with what Crankshaft does).
>
> The code is more or less the straightforward implementation. We
> will need to refactor that and extract common patterns once the
> remaining bits for full load/store support is in.
