Change caller_sp() to always point to the place after outgoing arguments.
Change deoptimizer to use absolute stack slot addresses for deferred HeapNumber's materialization.
(This is reapplication of r7504 with fix for mozilla testsuite failures).

Fix %NewObjectFromBound to correctly handle optimized frames (including those with inlined functions).
Fix %_IsConstructCall handling in hydrogen: when called from inlined function return false constant directly instead of emiting HIsConstructCall.
Fix success case in TraceInline.

The use of sizeof on FrameDescription to get to the additional allocated memory for the frame content relies on the padding of the FrameDescription. On IA32 Linux the FrameDescription is not padded but on ARM Linux it is padded to become 8 byte aligned. With a snapshot generated with the ARM simulator on IA32 Linux that contains one or more of the deoptimization tables the deoptimization did not work as the access to the frame content was one off between the C++ code and the generated code.

The previous implementation attempted to keep track of the needed
relocation size for deoptimization while generating the optimized
code. That was error prone. This patch moves the relocation resizing
to the deoptimizer as the last step of creating an optimized code
object.
The down side to this approach is that two relocation information byte
arrays are created for all optimized functions that do not have enough
relocation space for lazy deoptimization.

Record a safepoint with a deoptimization id for throw in optimized code. We
don't seem to much care what the AST ID is because we will not be using it
for lazy deoptimization (throw doesn't return to the point of throw). For
hygiene we use the actual ID of the throw expression. Throw is no longer a
control-flow instruction, but it's followed by an unconditional abnormal
exit. This is required to insert a simulate between the throw and the exit.
Make our optimized treatment of Function.prototype.apply act like a call and
have side effects. This ensures that it will get a lazy deoptimization
environment. Use that deoptimization ID in the safepoint for the call.
Deleting a property was also missing a deoptimization ID, though there was a
deoptimization environment assigned to the instruction. Record the
environment and use the deoptimization ID at the safepoint.

Change OSR stack check patching to use the stack check table to iterate over the calls to stack guards platform independent. Introduce Deoptimizer::PatchStackCheckAt for each platform to perform the platform specific patch at a given pc.

files. On ARM it is not enough to iterate the relocation information
because that will only give us access to the constant pool and not to
the place in the instruction stream where the target in the constant
pool is called.

objectprint=on (defaults to off) option (which defines OBJECT_PRINT).
2. Added the ability to print objects to a specified file instead of
just stdout.
3. Added a use_verbose_printer flag (true by default) to allow some
object printouts to be less verbose when the flag is false.
4. Fixed a bug in VSNPrintF() where it can potentially write into an
empty char vector.
