Reason for revert:
Waterfall redness.

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.

When compiling on a laptop I like to concatenate the small test files.
This makes a big difference to compile times. These changes make that
easier.
