Re-enable using push instructions for syncing the virtual frame.
This change fixes the problem with the original version of this approach
(r3032) that may lead to a corrupted stack if we would invoke spilling during
syncing a large SMI constant (unsafe SMIs) in the virtual frame.
The new code for storing unsafe SMI constants does not use an extra temporary
register. This prevents the compiler from ever having to spill during a
virutal frame sync operation.
For storing a large SMI constant we previously generated:
mov ecx, (large_smi & 0x0000ffff)
xor ecx, (large_smi & 0xffff0000)
push ecx
we now generate:
push (large_smi & 0x0000ffff)
or [esp], (large_smi & 0xffff0000)
Not using a temporary register avoids spilling within an nvocation
of VirtualFrame::SyncRange.

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_

Fix xssue 492: ARM debug crash: mozilla/ecma/FunctionObjects/15.3.1.1-3
When the number of parameters times 4 (kPointerSize) to a function cannot be encoded in 12 bits the return sequence gets one more instruction. Changed the assertion to check for this case.

Reverting 3174. Aka reapplying 3150, 3151 and 3159. Aka api accessor

* Do a GC in mksnapshot to get rid of some extraneous junk.
* Make snapshot more compact by coding the tag and the space
in one byte. Contract some common sequences to one byte.
* Use back references only within one page. Index from the
start of the space otherwise.
* Serialize Smis as raw data rather than int-encoding them.
This takes a little more space but is faster.

Insert call to CodeForFunctionPosition in the ARM code generator.
(== SetFunctionPosition in the top-level compiler)
IA32 and X64 already do this at the beginning of CodeGenerator::gencode

Begin using the top-level code generator for code that is inside
directly-applied function literals that are themselves compiled with
the top-level code generator.
The choice is guarded by a test that the function is anonymous (thus
not expected to be recursive) and not in a loop.
A compilation hint is set in the shared function info and used to make
the choice.

Fix a latent bug in the top-level compilation of function calls.
Calls to a non-global variable would go through the "call to a global"
path, rather than the "call to an arbitrary (other) expression" path.
