d07a2eb806 Rename ASSERT* to DCHECK*. 
This way we don't clash with the ASSERT* macros
defined by GoogleTest, and we are one step closer
to being able to replace our homegrown base/ with
base/ from Chrome.

018ef484b9 More OStreamsUse OStreams more often. 
This is a mostly mechanical CL (more than 90% Emacs macros and
query-replace-regexp) moving FILE*/StringStream*-based APIs to
OStream-based APIs. There are a few places where this had to stop,
otherwise the CL would be even bigger, but this can easily and
incrementally cleaned up later.

d7934d1fbe Start using OStreams. 
Note that until everything is OStream-based, there are a few places
where we have to do some impedance matching. A few accessors had to be
const-corrected on the way.

8f170a66e7 Improve positions tracking inside the HGraphBuilder. 
Instead of tracking simple absolute offset from the start of the script like other places do, track a pair of (inlining id, offset from the start of inlined function).

This enables us to pinpoint with inlining path an instruction came from. Previously in multi-script environments we emitted positions that made very little sense because inside a single optimized function they would point to different scripts without a way to distinguish them.

Start dumping the source of every inlined function to make possible IR viewing tools with integrated source views as there was previously no way to acquire this information from IR dumps. We also dump source position at which each inlining occured.

Tracked positions are written into hydrogen.cfg as pos:<inlining-id>_<offset>.

Flag --emit-opt-code-positions is renamed by this change into --hydrogen-track-positions to better convey it's meaning.

In addition this change assigned global unique identifier to each optimization performed inside isolate. This allows to precisely match compilation artifacts (e.g. IR and disassembly) and deoptimizations.

cd5ea74700 Replace 'operator*' with explicit 'get' method on SmartPointer 
Made operator* return reference to the raw type, not pointer. New method 'get()' should be used when raw pointer is needed.

Also removed useless inline modifier from the SmaprtPointer methods and added const modifier to the methods that don't change smart pointer.

Made ~SmartPointerBase protected to avoid accidental calls of the non-virtual base class's destructor.

adae3f77ec Allow redirecting disassembly and deoptimization traces into a file. 
This is controlled by two flags:

--redirect_code_traces
--redirect_code_traces_to=<filename>

When redirection is enabled but --redirect_code_traces_to is not specified traces are written to a file code-<pid>-<isolate>.asm. This mangling scheme matches hydrogen.cfg and allows easy discovery of compilation artifacts in a multi-V8 environment (e.g. when compilation is traced from inside Chromium).

D8 defines --redirect_code_traces_to=code.asm similar to hydrogen.cfg redirection.

bdeaf7514a Enable preaging of code objects when --optimize-for-size. 
This change means that code which is never executed is garbage collected immediately, and code which is only executed once is collected more quickly (limiting heap growth), however, code which is re-executed is  reset to the young age, thus being kept around for the same number of GC generations as currently.

4c565138b5 Add tool to visualize machine code/lithium. 
In the process:
- Add a command-line flag --opt-code-positions to track source position information throughout optimized code.
- Add a subclass of the hydrogen graph builder to ensure that the source position is properly set on the graph builder for all generated hydrogen code.
- Overhaul handling of source positions in hydrogen to ensure they are passed through to generated code consistently and in most cases transparently.

5a4e0f1c79 Simplify and fix code aging. 
Making the code size predictable is hard, and to make things even more
complicated, the start of a function can contain various stuff like calls to a
profiling hook, receiver adjustment or dynamic frame alignment. Instead of
tackling all these problems separately, we now simply record the offset where
patching should happen later in the Code object itself.

The live registers are now only stored to the expression stack with the non pointer values being stored as smis (on the 32-bit platforms these values are assumed to be 31-bit max).

This makes the CEntryStub entry/exit code much simpler, and there is no longer any need for a mode (debug or normal) on it.

634fb9152c More precise break points and stepping when debugging 
Added support for more precise break points when debugging and stepping. To achieve that additional nop instructions are inserted where breaking would otherwise be impossible. The number of nop instructions inserted are sufficient to make place for patching with a call to a debug break code stub. On Intel that is 5 nop's for 32-bit and 13 for 64-bit. Om ARM 3 nop instructions (12 bytes) are required.

In order to avoid inserting nop's in to many places a simple ast checker have been added to check whether there are breakable code in a statement or expression. If it is possible to break in an expression no additional break enabeling code is inserted.

Added break locations to the true and false part of a conditional expression.

Added stepping tests to cover more constructs.

These changes are only in the full compiler.

Changed the default value for the option --debugger in teh d8 shell from true to false. The reason for this is that with --debugger turned on the full compiler will be used for all code in when running d8, which can be unexpeceted.

daf1ea3970 Avoid constant pool blocking for too long 
The generation of the deferred code for named property load where the load was inlined did a constant pool blocking for the whole deferred code. Having large numbers of this type of deferred code generated one ofter the other effectively blocked the constant pool for all the deferred code causing 

Removed the BeforeGenerate/AfterGenerate for the deferred code and made macro assembler StartBlockConstPool/EndBlockConstPool non-public. Re-introduced BlockConstPoolFor instead to use with BlockConstPoolScope to block some more instructions cross function calls.

Also handle the use of native code counters for inlined named property load.

931f0a031a Changed inlined property load detection on ARM 
Instaed of having a nop after all non-inlined calls to load IC use a different nop (mov r1, r1 instead of mov r0, r0) to detect an inlined load IC.

Added more infrastructure to the deferred code handling to make it possbile to block constant pool emitting in a deferred code block, including the branch instruction ending the deferred code block.

Addressed a couple of comments to http://codereview.chromium.org/1715003, including adding an assert to make sure that the patching of an ldr instruction is always possible.

If 'shell' is compiled with 'cppprofilesprocessor=on' and run
with '--prof' flag, top-down and bottom-up call trees are printed

This makes usage of cmov unnecessary.

f5523ecc6a Split the virtual frame into heavy and light versions. 
The heavy version is for x86 and x64.  The light version
is for ARM and MIPS.  Remove the elements_ array from the
virtual frame in the light version.  More simplifications
to come, followed by light register allocation.

a1ec99c05d - Remove function boilerplate objects and use SharedFunctionInfos in 
their place.
- Add one field to the SharedFunctionInfo to remember the number of
  literals used in this function.

e5f27966dc Add fuzzing support for inline runtime functions 
The inline runtime functions are now included in the fuzzing of the natives. The chack for the expected number of arguments passed have been moved to the parser which will generate a syntax error if a runtime function (either C++ or inline) is called with a different number of arguments than expected.

496868722f Added fast support for Math.pow. This simply calculates the result using the 
same method as the old powi version in runtime.cc and also checks if
the exponent is 0.5 or -0.5 in which case we calculate the square root or 
reciprocal value of the square root.
