original commit message:

  Eliminate special keyed load string stub in favor of uniform handlers.

  KeyedLoadIC installs a special case if the receiver is a string.
  Although there are several maps for strings, in practice we seem to
  be able to treat them individually because a given KeyedLoad site
  only sees 1-2 string types

original commit message:

  Removing ic.h from code-stubs.h

  CodeStubs use state types defined in ic.h, but this has the unfortunate effect of spreading ic.h all over the place. Instead, define these shared state types in ic-public.h and allow ic.h to concern itself with internal state change of the ICs.

  More work could/should be done here, but this is a first step.

original commit message:

  Added CallInterfaceDescriptors to all code stubs. A handful
  of code stubs are too complex to be described this way, and
  they are encoded with the macro
  DEFINE_NULL_CALL_INTERFACE_DESCRIPTOR().

  Along the way:
  * allowed inheritance of CallInterfaceDescriptors.
  * Defined static Register methods for some of the new
    CallInterfaceDescriptors. We could go a lot further here, but
    it doesn't have to be done immediately.
  * Added Representation arrays to some CallInterfaceDescriptors,
    especially where future hydrogen versions of the stubs could
    benefit from this knowledge.

original commit message:

  To aid vector-based load ic work, we need to be able to handle
  the megamorphic load case in hydrogen. A simple approach is to
  wrap the probe activity in a hydrogen instruction.

  The instruction is novel in that it always tail-calls away.
