Fixed deopt reasons in TaggedToI.

Every DeoptimizeIf should be preceded by a RecordComment explaining
the reason. In the long run, the reason should be an argument of
DeoptimizeIf, but we're not there yet.

On x87, things are a bit ugly due to some pushing/popping, so if
somebody feels inclined to improve this: Feel free. Probably the right
approach would be reloading instead of the push/pop horror.

Another thing is our inconsistent handling of the "done" continuation
of deferred code on the various platforms, I made tiny changes on the
way, but this should better be unified somehow, with all those
micro-optimizations removed.

We can only set resource constraints before the isolate is initialized.
Since in the future, we want to initialize isolates at construction

It's possible to later modify the stack limit, so introduce an
Isolate::SetStackLimit method for that.

The SetResourceConstraints method will be deprecated. Users should pass
ResourceConstraints to Isolate::New, and use Isolate::SetStackLimit to

Currently, a new isolate is created in an uninitialized state, and
several API methods will automatically initialize it. During this
uninitialized state, code event handlers and function entry handlers can
be attached to the isolate.

This CL deprecates SetFunctionEntryHook and moves the configuration of
those handlers to the Isolate factory method.

This will allow for initializing the Isolate at creation time in the
future.

Users of V8::SetFunctionEntryHook should pass the entry hook to
Isolate::New instead. V8::SetJitCodeEventHandler should either be passed
to Isolate::New as well, or (if startup events are not required) invoked
via the Isolate.

The change also fixes bunch of tests, mostly by adding more deoptimization points.

Fix Smi vs. HeapObject confusion in HConstants.

X87: Eliminate Turbofan shims with CodeFactory

port r23877.

original commit message:

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.

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.

  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.
