Reviewers: Toon Verwaest,

Message:
Hi Toon, here is the second in the series of two CLs we discussed, this one
converting the indexed interceptor to a handler.

The handler is simpler because it doesn't need to introspect on the map, it's just a smi-check and tail call. I thought about Hydrogenizing it, but I'd have
to add tail call support to CallRuntime. Could do, could do. WDYT? PTAL!

Description:
Convert KeyedLoad indexed interceptor case to a Handler.

Currently, KeyedLoads on objects with indexed interceptors are handled with a
special stub. Instead, key on the map and handler mechanism for more uniform
treatment.
