MIPS: Turbofan needs a code handle and a CallInterfaceDescriptor.

Port r23877 (bd09296)

Original commit message:
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.

X87: Encapsulate megamorphic load/tail-call in hydrogen

port r23772.

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.

X87: Added CallInterfaceDescriptors to all code stubs.

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.

Add script streaming API.

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.
