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.

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.

This implements parsing for ClassExpression and ClassDeclaration.
The runtime is not yet implemented and the value is currently

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

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
later modify the stack limit.
