b0a852e8c2 [turbofan] Add new JSFrameSpecialization reducer. 
The JSFrameSpecialization specializes an OSR graph to the current
unoptimized frame on which we will perform the on-stack replacement.
This is used for asm.js functions, where we cannot reuse the OSR code
object anyway because of context specialization, and so we could as well
specialize to the max instead.

It works by replacing all OsrValues in the graph with their values in
the JavaScriptFrame.

The idea is that using this trick we get better performance without
doing the unsound backpropagation of types to OsrValues later. This is
the first step towards fixing OSR for TurboFan.

1cd60451de [turbofan] Greedy allocator refactoring. 
Separated core greedy allocator concepts, exposing the APIs we would want to continue working with. In particular, this change completely reworks CoalescedLiveRanges to reflect the fact that we expect more than one possible conflict, scrapping the initial design of the structure. Since this is a critical part of the design, this change may be thought of as a full rewrite of the algorithm.

Reduced all heuristics to just 2 essential ones: split "somewhere", which we'll still need when all other heuristics fail; and spill.

Introduced a simple primitive for splitting - at GapPosition::START. The goal is to use such primitives to quickly and reliably author heuristics.

I expected this primitive to "just work" for any arbitrary instruction index within a live range - e.g. its middle. That's not the case, it seems to upset execution in certain scenarios. Restricting to either before/after use positions seems to work. I'm still investigating what the source of failures is in the case of "arbitrary instruction in the range" case.

I intended to document the rationale and prove the soundness of always using START for splits, but I will postpone to after this last remaining issue is resolved.

733a246386 [turbofan] Proper dead code elimination as regular reducer. 
The three different concerns that the ControlReducer used to deal with
are now properly separated into

  a.) DeadCodeElimination, which is a regular AdvancedReducer, that
      propagates Dead via control edges,
  b.) CommonOperatorReducer, which does strength reduction on common
      operators (i.e. Branch, Phi, and friends), and
  c.) GraphTrimming, which removes dead->live edges from the graph.

This will make it possible to run the DeadCodeElimination together with
other passes that actually introduce Dead nodes, i.e. typed lowering;
and it opens the door for general inlining without two stage fix point
iteration.

To make the DeadCodeElimination easier and more uniform, we basically
reverted the introduction of DeadValue and DeadEffect, and changed the
Dead operator to produce control, value and effect. Note however that
this is not a requirement, but merely a way to make dead propagation
easier and more uniform. We could always go back and decide to have
different Dead operators if some other change requires that.

Note that there are several additional opportunities for cleanup now,
i.e. OSR deconstruction could be a regular reducer now, and we don't
need to use TheHole as dead value marker in the GraphReducer. And we can
actually run the dead code elimination together with the other passes
instead of using separate passes over the graph.  We will do this in
follow up CLs.

80a6e53935 [turbofan] Move graph trimming functionality to dedicated GraphTrimmer. 
Up until now that was still mixed with control reduction in the
ControlReducer. This separation allows us to remove the horrible
Reducer::Finish hack and also do graph trimming at more appropriate
places in the pipeline (i.e. trim dead nodes after generic lowering,
which can also make nodes dead).

4e0b7b0cf5 Separated the new register allocator in its own files. 
Opportunistically removed GreedyAllocator::TryReuseSpillForPhi because it is actually unsuitable for Greedy. It was copied from Linear and it relies on hints, however, the current implementation of hints assumes linear scan.

This change doesn't aim to address performance nor correctness for Greedy.

4cf578a1ea Make v8 snapshot public in component build. 
This was already public in a non-component build. This means that targets
dependent on the "v8" target can take the results of the snapshot as inputs.

This also renames the component mode checking from keying off of the
component_mode string to checking the is_component_build flag, which is now the
recommended way to do this check.

e2e47f30be [turbofan] First step towards sanitizing for-in and making it optimizable. 
In a nutshell: The FILTER_KEY builtin is gone, and was replaced by a
simple runtime call to ForInFilter, which does everything and is even
cheaper (because FILTER_KEY used to call into the runtime anyway).
And ForInFilter returns either the name or undefined, which makes it
possible to remove the control flow construction from the AstGraphBuilder,
and thereby make both the initialization and the per-loop code of for-in
optimizable later (in typed lowering).

570fca61fc Re-land: Make V8 extras a separate type of native 
Instead of making them an extra option that gets passed in and compiled
at the end of the natives file for a given run of js2c, we now make them a
separate run of js2c with a separate natives file output.

This natives file output is then compiled in the bootstrapper. It is not part
of the snapshot (yet), but instead is treated similar to the experimental
natives, just without any of the complexity that comes from tieing the
behavior to flags. We also don't need counterparts to
InitializeExperimentalGlobal and InstallExperimentalNativeFunctions (yet?).

This fixes the issue with https://codereview.chromium.org/1129743003 by making
the dummy file that is generated for snapshots with no extras (or no experimental
features) nonempty.

978acb8d5e Adjust the visibility of the standalone targets in the GN build. 
As part of the migration from GYP->GN, we want to make sure that we
can track when new targets are added to either the GYP or GN builds
and that we are building everything we expect to build.

In GN, unlike GYP, if a build file gets referenced from other files,
building 'all' will cause every target to be built in it. This means in
particular, that we can end up trying to build targets that are not
necessarily intended to be visible to the rest of the build. To get
around this, any target that is defined but hidden (like 'v8_snapshot',
in V8's case) should still be visible to a top-level target called
"//:gn_visibility".

optimization that is actually testable. The instruction selection can
still fall back to a regular if the platform constraints don't allow to
emit a tail call (i.e. the return locations of caller and callee differ
or the callee takes non-register parameters, which is a restriction that
will be removed in the future).

Also explicitly limit tail call optimization to stubs for now and drop

The libdl library is already included on target builds of Android and needs
to be added to the build command line with a particular order to avoid
undefined references in other libraries. Fix this by only explicitly including
it in host builds and relying on the implicit inclusion on target builds.

Also remove the librt hack which is not longer necessary due to the AOSP build
bot having been removed.

ca3abde2fa [turbofan] Variable liveness analysis for deopt. 
This change introduces a liveness analyzer for local variables in frame states.

The main idea is to use the AstGraphBuilder::Environment class to build the control flow graph, and record local variable loads, stores and checkpoints in the CFG basic blocks (LivenessAnalyzerBlock class).

After the graph building finishes, we run a simple data flow analysis over the CFG to figure out liveness of each local variable at each checkpoint. Finally, we run a pass over all the checkpoints and replace dead local variables in the frame states with the 'undefined' value.

cd67e97a7e [turbofan] Cache for reusing parts of value vector nodes in frame states. 
Instead of the current approach of storing flat vectors in frame states (and possibly reusing the last vector in AST graph builder), this change list builds a tree for the values and tries to reuse the nodes for different frame states. At the moment, we only use this for the local variable part of frame state, but nothing prevents us from using this for all parts.

This change provides two new classes: one for creating the tree (StateValuesCache) and one for iterating the trees (StateValuesAccess).

ad5630db87 Fix the toolchain used to build the snapshots in GN. 
We need the v8 snapshot to be compiled on the host cpu (the
machine doing the build), but using generated code that has the
same pointer size as the target_arch; i.e., for 32-bit arm builds,
we need to use a 32-bit x86 host binary, not a 64-bit host binary.

The easiest way to ensure that this happens is to just specify
a custom toolchain in GN to use to build the snapshot.

27e8a455df Rename Interface to ModuleDescriptor 
ModuleDescriptor will end up holding the set of data described in the
spec as a "Module record". This introduces a little bit of confusion
with ModuleInfo, but I hope that'll become clearer over time.

acd9c46ca7 [turbofan] Optimize certain chains of Branch into a Switch. 
This adds a new ControlFlowOptimizer that - for now - recognizes chains
of Branches generated by the SwitchBuilder for a subset of javascript
switches into Switch nodes. Those Switch nodes are then lowered to
either table or lookup switches.

Also rename Case to IfValue (and introduce IfDefault) for consistency.

ControlReducer only runs really early and really late in the pipeline

Currently, the behaviour is essentially the same as ES262's version, however this changes when internal structures

Symbol.toStringTag is exposed publicly.

e4c6f9488e Implement graph trimming in ControlReducer. 
Trimming the graph consists of breaking links from nodes that are not reachable from end to nodes that are reachable from end. Such dead nodes show up in the use lists of the live nodes and though mostly harmless, just clutter up the graph. They also can limit instruction selection opportunities, so it is good to get rid of them.

This CL is one half of the ControlReducer functionality, the other half
being branch folding.

0dd69ec439 Allow identifier code points from supplementary multilingual planes. 
ES5.1 section 6 ("Source Text"):
"Throughout the rest of this document, the phrase “code unit” and the
word “character” will be used to refer to a 16-bit unsigned value
used to represent a single 16-bit unit of text."

This changed in ES6 draft section 10.1 ("Source Text"):
"The ECMAScript code is expressed using Unicode, version 5.1 or later.
ECMAScript source text is a sequence of code points. All Unicode code
point values from U+0000 to U+10FFFF, including surrogate code points,
may occur in source text where permitted by the ECMAScript grammars."

This patch is to reflect this spec change.

CodeStubs use state types defined in ic.h, but this has the unfortunate effect of spreading ic.h all over the place. Instead, define these shared state types in ic-public.h and allow ic.h to concern itself with internal state change of the ICs.

More work could/should be done here, but this is a first step.

ca16bb7ae2 Split out libplatform into a separate libary 
Also remove the "use default platform" compile flag. Instead, the embedder
has to provide the platform.

Change all binaries to use the default platfrom from libplatform.

Unless --job-based-sweeping is passed, nothing uses the platform yet, so
nothing will break for embedders (yet).

b66afe30fe Add a basic gn file for V8 
Currently, the gn support is incomplete and only works from within a

See https://code.google.com/p/chromium/wiki/gn for details

We move the BUILD.gn file to v8 nevertheless to make renaming files
easier, as the chromium CQ already now checks the gn build.
