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.

Also removed the interface-printing flags. We probably want
Module-printing flags, but that can wait until we have more
Module-related structures.

316f860a6b Revert of Revert of Revert of Add d8 target to the GN build. (patchset #1 id:1 of https://codereview.chromium.org/833563004/) 
Reason for revert:
This is now really blocking the roll.  I believe it's just missing

    configs -= [ "//build/config/compiler:chromium_code" ]
    configs += [ "//build/config/compiler:no_chromium_code" ]

in the d8 config but I have no way to check.

disabling snapshots allows us to run V8 just fine which

Mojo/Sky are GN-only so we depend on the V8 GN build even if

ee98a1d760 [turbofan] Introduce CommonOperatorReducer. 
The CommonOperatorReducer currently takes care of redundant Phis,
EffectPhis and Selects. This functionality overlaps with ControlReducer,
but is required to make certain optimizations effective, since the
ControlReducer only runs really early and really late in the pipeline
and therefore other reducers aren't reapplied properly after redundant
phi/select elimination.

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.

These sentinels were in the wrong place, living in only tangentially related class TypeFeedbackInfo, but they codify state in the TypeFeedbackVector.

The TypeFeedbackVector is poised to host significant functionality. While it
remains a FixedArray under the covers, we need a place to hold logic and

a4176d2052 Removing ic.h from code-stubs.h 
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.

* Make context specialization clean up after itself.
* Add UpdateToAndIncrement to Inputs::iterator.
  Uses:iterator already provides this member function.
* Allow next node id in graph to be set.

to reduce the size of the compiled binary for space constrained

2709e30562 Revert "Fix gn build". 
This was reverted due to GN build failures while rolling V8 into
Chromium. Locally reproducing it verified that this makes the GN
build pass again.

ba9f391bc0 Support external startup data in V8. 
[Retry of crrev.com/293993021, which caused problems with 'ninja all' in Chromium. First patch set if a clean apply
of crrev.com/293993021. Subsequent sets are the actual fix
for that issue.]

If the embedder chooses, the 'natives' (library sources) and the
precompiled startup blob can be written to files during the build
process and handed over to V8 at startup. The main purpose would be
to reduce the size of the compiled binary for space constrained
platforms.

The build-time option is off by default. Nothing should change if
it's not enabled.

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

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.
