868470ddc9 [strong] Adding regression cases which should always continue working. 
1) Mutually recursive functions
2) Strong code using non-strong var before declaration.

These test cases ensure that we don't accidentally kill these wanted behaviors
when adding restrictions to strong mode.

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).

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.

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.

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

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.

d962c092f3 Revert of [turbofan] Fix bunch of tests failing with --turbo-deoptimization. (patchset #1 id:1 of https://codereview.chromium.org/786333004/) 
Reason for revert:
This changes layout test expectations. I ran a bisect over the layout tests:

Bad:
http://build.chromium.org/p/client.v8/builders/V8-Blink%20Linux%2032/builds/1600

Good:
http://build.chromium.org/p/client.v8/builders/V8-Blink%20Linux%2032/builds/1599

If this is intentional please first land a CL with manualrebaseline test expectations for the changed tests and then reland.
