d1b5aa0716 Removed most of the bogus CompilationInfo constructor calls.
A CompilationInfo constructed from just an Isolate* and a Zone* is in
weird an inconsistent state (calling e.g. flags() on it will crash),
so we need to avoid them. This CL removes almost all of them, the
remaining 2 call sites in (for testing only) will be handled in a
separate CL. Things which have been changed:

  * Linkage is basically a decorator for CallDescriptor now.

  * ChangeLowering doesn't need Linkage at all.

  * JSGenericLowering doesn't need a full CompilationInfo*, just a
    single flag.

  * JSContextSpecializer doesn't need the full CompilationInfo, just a
    Context.

  * Removed unused CompilationInfo from SimplifiedLoweringTester.

This nicely decouples things already a bit more, but there's still
work to do...

a18b797fd9 Enable compiling mjsunit tests as ES6 modules
Adding the line "// MODULE" to an mjsunit file will now cause
run-tests.py to prefix the test case with "--module" in the
d8 commandline.

d8 has itself been updated to treat files preceded with "--module" as
modules (that is, it compiles them with ScriptCompiler::CompileModule,
and turns on --harmony-modules).

5d68529be2 Parsing: Make Scope not know about Isolate.
Scope, like Parser, must be able to operate independent of Isolate and the V8
heap (for background parsing). After the heap-independent phase, there is a heap
dependent phase, during which we do operations such as scope anaylysis.

This CL makes the phases explicit by not telling Scope about the Isolate too
early (during the heap-independent phase, Scope should know nothing about
Isolate). This decreases the probability of accidental code changes which would
add heap-dependent operations into the heap-independent phase.

86cae1633c Propagate DeoptInfo to cpu-profiler
1) Deoptimizer::Reason was replaced with Deoptimizer::DeoptInfo
because it also has raw position. Also the old name clashes with DeoptReason enum.

2) c_entry_fp assignment call was added to EntryGenerator::Generate
So we can calculate sp and have a chance to record the stack for the deopting function.
btw it makes the test stable.

3) new kind of CodeEvents was added to cpu-profiler

4) GetDeoptInfo method was extracted from PrintDeoptLocation.
So it could be reused in cpu profiler.

70079dab13 Add basic compilation support for modules
This adds an "experimental" API hook (v8::ScriptCompiler::CompileModule)
allowing compilation of modules. The code gen is incredibly basic: the
module body is represented by a Block in the AST. But this at least gets
more of the pipeline working, and opens the door to writing mjsunit tests
(once d8 is modified to support module compilation).

5c56665059 PreParser / Parser consistency: Make PreParser aware of Zone and AstValueFactory.
Previously it just had hacks to have NULLs instead of them and pretended to know
nothing about Zone. The hacks provide no real benefit (probably historically
based on some weird misconception about the relationship between Zone and
Isolate), and make it harder for the PreParser to start to know more about
variables and scoping.

308d913a92 Contribution of PowerPC port (continuation of 422063005) - PPC dir update
Contribution of PowerPC port (continuation of 422063005, 817143002 and 866843003)
This patch brings the ppc directories up to date with our repo. We have
removed 5 individual optimizations which require changes in both the ppc and common
directories so they can be more easily reviewed on their own in subsequent patches.

Subsequent patches will cover:
- individual optimizations for PPC (5)
- remaining AIX changes not resolved by 4.8 compiler (4.8 is only recently available
for AIX)
- incremental updates required to ppc directories due to platform specific changes
made in google repos while we complete the above steps.

With the update there are still some timeouts seen when run in simulated mode which
may be a result of the missing optimizations.  Once we have the optimizations in
we will review the simulation results and address/exclude tests as necessary so that
the simulated runs are clean.

0e3b5386ae Scanner / Unicode decoding: use size_t instead of unsigned.
size_t is the correct data type for this purpose. Our APIs (in particular
ExternalSourceStream::GetMoreData) are already using it, and there were some
static_casts to convert between them.

This CL doesn't intend to fix all of V8, just the minimal sense-making part
around scanner character streams.

cd661fdc27 Fix issue with multiple properties and emit store.
We used to have a parse error for conflicting property keys. This check
was removed to match ES6 (SpiderMonkey & Chakra already made this change).
Since this check was removed we ended up with a few new cases when
generating code. For example, accessors always generated code even if
those should have been shadowed by a data property.

6fc97a1965 Retry "Use a WeakCell in the CallIC type vector."
The first try failed because I needed to make a better distinction
between clearing ICs according to policy at GC time or unconditional
clearing (say, via %ClearFunctionTypeFeedback).

It was also blocked by an issue in super constructor calls.
This fix (https://codereview.chromium.org/892113002/) needs to land
before checking in this CL.

c7851da4ae Introduce LanguageMode, drop StrictMode.
This enables adding more language modes in the future.

For maximum flexibility, LanguageMode is a bitmask, so we're not restricted to
use a sequence of language modes which are progressively stricter, but we can
express the language mode as combination of features.

For now, LanguageMode can only be "sloppy" or "strict", and there are
STATIC_ASSERTS in places which need to change when more modes are added.

LanguageMode is a bit like the old LanguageMode when "extended" mode was still
around (see https://codereview.chromium.org/8417035 and
https://codereview.chromium.org/181543002 ) except that it's transmitted through
all the layers (there's no StrictModeFlag).

d8cfbc633d [turbofan] Split pure nodes in the scheduler if beneficial.
If a (pure) node has two or more uses, but there exists a path from the
common dominator of these uses to end, which does not contain a use,
then we split the node such that no unnecessary computation takes place.
Note however, that this only applies if the node cannot be hoisted out
of a loop.

f1ba8d8f86 Contribution of PowerPC port (continuation of 422063005) - AIX Common1
Contribution of PowerPC port (continuation of 422063005 and 817143002). This patch covers
the key changes needed to the common files needed to support AIX. Subsequent
patches will cover:
- changes to update the ppc directories so they are current with the changes
in the rest of the project.
- remaining AIX changes not resolved by 4.8 compiler
- individual optimizations for PPC

This is based off of the GitHub repository

b004b1d821 Move object literal checking into checker classes
This removes the duplicate property check from object literals.

Instead we repurpose the ObjectLiteralChecker into two cases, implemented
by two subclasses to ObjectLiteralCheckerBase called ObjectLiteralChecker
and ClassLiteralChecker.

The object literal checker now only checks for duplicate __proto__ fields in
object literals.

The class literal checker checks for duplicate constructors, non constructor
fields named constructor as well as static properties named prototype.

91b87e7a28 Do not create unresolved variables when parsing arrow functions lazily
Arrow function parameter lists are parsed as expressions. When an identifier
is found a VariableProxy is created and added to the list of unresolved
variables for the scope. When parsing a function lazily, the scope has been
already resolved, so with this patch only the VariableProxy is created,
without adding it as an unresolved variable in the scope.

aeb3a71740 Begin modernization of --harmony-modules
The approach taken in this CL is to incrementally move toward the
currently-specced version of modules in ES6. The biggest change in this
patch is separating the parsing of modules from the parsing of scripts,
getting rid of the 'module' keyword and thus disallowing modules-in-scripts
as well as modules-in-modules.

The syntax supported by import/export declarations has not yet been significantly
changed, with the major exception being that import declarations require a string
as the 'from' part.

Most of the existing tests have been disabled, with a first new test added
in cctest/test-parsing.

59a02ebdbe [turbofan] Ensure that NTLs are always properly connected to the end.
Up until now we used a special Terminate node to artifically connect non
terminating loops to the End node, but this was kind of adhoc and didn't
work for the CFG. So without all kinds of weird hacks, the end block in
the CFG will not be connected to NTLs, which makes it impossible to
compute post dominance / control dependence in the current setting.

So instead of Terminate, we add a special Branch to NTLs, whose
condition is the special Always node, which corresponds to True, except
that it cannot be folded away. This way we don't need any special
machinery in the scheduler, since it's just a regular Branch.
