This reverts commit 347092ac.

Not a clean revert, since other changes got baked on top, but rather
a manual removal of LoadLazyICParameters.

Reason for revert: Seems to actually regress bindings perf tests (see
bugs and https://chromeperf.appspot.com/group_report?rev=62539), doesn't
seem to improve performance elsewhere, and increases complexity.

Original change's description:
> [ic] Load name/context lazily in LdaNamedProperty
>
> Introduces LazyLoadICParameters which allow a LazyNode for context and
> name. These aren't used on the fast path, so we want to avoid reading
> them for both performance and register pressure reasons.
