963d72ff57 Revert r3032 that uses push instead of 'sub esp, size'. This change 
leads to stack corruption in 32-bit version of V8.

See http://code.google.com/p/chromium/issues/detail?id=27227 for a
reproducible case.

Since this is only an issue on 32-bit V8 I think this has got
something to do with the UnsafeSmi handling that we do on ia32.  I'm
reverting for now so we can push a fix, but we should track down the
issue and create a regression test for this.

091c7a2306 Fixed bug in while-loops that caused an assertion to fail. 
We forgot resetting true-/false-label to NULL after evaluating the 
condition expression in dowhile- and while-loops. 
This change fixes this.

This causes an assertion to fail in VisitIfStatement whenever there is an 
if-statement after a while-loop before. e.g. like in:

  var i=0, j=0;
  while(j<5) { j++; }
  if (i ==0 ) { j++; }

6a3921fc0e Keep natives source code in external strings instead of putting 
it in regular flat strings that are part of the snapshot.
After this change we don't need libraries-empty.cc any more.  In
this change libraries-empty.cc is just a the same as libraries.cc
and the scons build builds it but does not use it.  We can move
in stages to a situation where it is not generated at all for all
the build systems that we have.

41d6cae46d 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.

b5a19c1036 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

                 \
                  \---->   handler
 [C++ address]   <------    next_


On actual hardware the C++ try catch handlers continue to be directly
linked.

77a71c90c7 Fix issue 491: constantpool dump violates ARM debugger assertion for return point 
The generation of the return sequence is now protected from having the constant pool emitted inside of it in both compilers.

ff0d885b95 Emitting the common return sequence in the top-level compiler in one function for each platform. 
I factored out the code for emitting the return sequence since we had this code duplicated in the top-level compiler.

34dee0319c Remove the typeof state threaded through the code generator. It was 
used to signal that an expression was the immediate subexpression of
typeof, or (?) in the arm of a conditional expression itself in the
typeof state.

It was inconsistently consulted.  It was not used for property loads,
but only for slot loads.  This means that we matched the Webkit JSC
(not Spidermonkey) behavior for:

typeof(true ? x : y)  // throws ReferenceError

and we matched the SpiderMonkey behavior (not JSC) for:

with ({}) { typeof(true ? x : y) }  // ==> "undefined"

Now we are expected to match the JSC behavior in all cases.
