Reapply: Never use classic code generator.
...
Crankshaft is now the default on all platforms. This is the first
patch on the way to removing the classic code generator from the
system.
This time with no removal of the crankshaft flag. --nocrankshaft is
not at all the same as --always-full-compiler which I had used instead
for testing. That was what caused timeouts on the buildbots because of
repeated attempts to optimize hot functions. It makes sense to keep
the crankshaft flag in case you want to run only with the full
compiler and with no adaptive compilation.

Fix issue 493: Infinite loop when debug break is set when entering function.apply.
...
In the generated code for function.apply there was a loop checking the stack limit for interruption. This loop would call into the runtime system to handle interuption and keep running until there was no interruption. However if the interuption was debug break the runtime system would never clear the interruption as debug break is prevented in builtins are prevented and the assumption here was that returning with the debug break flag set would move execution forward.
Renamed initial_jslimit and initial_climit to real_jslimit and real_climit. Renamed a few external references related to the stack limit as well.
Exposed the real stack limit to generated code to make the stack check when entering function.apply use the real stack limit and not the stack limit which is changed to signal interruption.
Added the real stack limit to the roots array.

Rework the way we handle the fact that the ARM simulator uses a
...
separate JS stack.
In exception handling, we need to be able to compare addresses into
the JavaScript portion of the stack with the address of a C++ handler
on the stack. Since the stacks are separate on the simulator, we need
a JavaScript stack address corresponding to a C++ try catch handler in
order to perform valid address comparisons.
On the simulator, we now link the C++ try catch handlers indirectly
through the JS stack and use the JS stack indirection address for
comparisons.
JS C++
handler
[C++ address] <------ next_
\
\
\----> handler
[C++ address] <------ next_
On actual hardware the C++ try catch handlers continue to be directly
linked.

Remove the high-priority flag from IdleNotification() since
...
it is a strange API and unused anyway.
When we roll this to Chrome, we'll need a small chrome patch
to fix Chrome's usage of the API.

The error cases were returning false instead of true.
...
So if the caller does something like:
while(!IdleNotification())
it could spin forever if v8 were not initialized.
I'd like to further remove the is_high_priority flag,
because it is not in use. Mads - is there any reason
not to remove it?
