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.

aeec653f49 Revert of Add WeakMap to v8.h (patchset #3 id:40001 of https://codereview.chromium.org/886473005/)

4e9e1eedf1 [V8] Added line, column and script symbols for SyntaxError
For exception in promise we generate v8::Message API object from exception object. And in cases of Syntax or Reference Error we don't have enough information in exception object - we can't restore Error location from top stack frame.
In this patch three aditional private fields introduced for exception object. In case of Syntax Error we store line, column and script on Exception object and receive this information when restoring message.

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.

is found a VariableProxy is created and added to the list of unresolved

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.

- Punched a hole in the config to be able to get to the isolate so

feffccca22 Profiler improvements
(1) --prof-cpp: Collects ticks like --prof, but ignores code creation events to reduce distortion (so all JS ticks will be "unaccounted"). Useful for profiling C++ code.
(2) --timed-range flag for tick processor: Ignores ticks before the first and after the last call to Date.now(). Useful for focusing on the timed section of a test.

Bad:

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.

The test fails on XP only, so let's tentatively raise the stack limit more. We probably need to investigate what a tighter limit might be and (more importantly) what the underlying reason for the failure is.

Hopefully 1800kB is enough, we can't test this via try jobs, because we don't have XP try bots. :-/

22e6958d63 Fix remaining issues in the custom snapshot.
Math functions:
Some Math functions require typed arrays for their implementation. The embedded
script may call those Math functions. The serializer needs to deal with this.
Added assertion to make sure no other typed array is created when snapshotting.

Number-string cache:
We assume that the initial snapshot does not expand the number-string cache.
This is no longer true for custom heap snapshots.

Bound functions:
Bound functions store the bound arguments in a COW fixed array, including the
bindee function. COW arrays are serialized into the startup snapshot and
referenced in the partial snapshot via partial snapshot cache. However, the
bindee function is context-dependent and must not be part of the startup
snapshot. There is no need for bound functions to use a COW array though.

(Debug builds have --enable-slow-asserts, and with slow asserts each
assignment to the array in the prepare function will trigger a check
over the entire array. This turns it into n^2 work, for reasonably
large n.)
