  Turbofan needs a code handle and a CallInterfaceDescriptor. At the same time we spread knowledge about how to create the initial IC code object too widely. Consolidate code creation and unify it with a descriptor via CodeFactory.

port r23854.

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.

  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.

Blink will use this API to stream script data into V8 as the scripts
load. During loading, V8 can already parse the scripts. They will be then
compiled and executed when the loading is complete.

Parser had unnecessary member pointers to stuff stored in the
CompilationInfo (which Parser also points to).

As we add more parsing code paths (in particular, script streaming), this gets
confusing and Parser and CompilationInfo can get out of sync.

The crash happens in DebugEventListener that gets called for an unhandled exception thrown by TryCatch.ReThrow().

In DevTools some parts of DebugEventListener are implemented in JavaScript, thus we should allow JavaScript execution while handling ReThrow exception in debugger.
