722e19efd6 Fixing --verify-predictable mode.
This CL fixes several sources of non-predictability by making Platform::MonotonicallyIncreasingTime() the only bottleneck for all time-querying functions and providing PredictablePlatform implementation.

fb9ad89fea [Interpreter]: Add ignition blacklist to mjsunit.status and test262.status.
Adds a blacklist of tests which are currently unsupported or broken in Ignition to
the mjsunit and test262 test status.

Also removes --ignition-script-filter flag, and adds a
--ignition_fallback_on_eval_and_catch flag which fallsback to fullcodegen for
functions which call eval or contain a catch block.

17a4e20e0d Revert of [turbofan] Enable general purpose inlining. (patchset #2 id:20001 of https://codereview.chromium.org/1416873007/ )
Reason for revert:
As discussed with Benedikt: Disable --turbo-inlining again because it tanks Jetstream.

2fa4732739 Re-ship @@toStringTag
It was originally shipped in https://crrev.com/eef2b9b09723ba1dae3ec0172341e93e9030ada0,
but was reverted due to poor interaction with Blink.

That interaction seems to be fixed thanks to changes to the V8 API
and to @@toStringTag handling on access-checked objects.

2a866bc4dd Stage --harmony-destructuring and --harmony-default-parameters
Since enabling destructuring already implies enabling default parameters,
there's not a good way to separate these two. Luckily, they're both
feature-complete (save for destructuring assignment).

This causes us to pass an additional 24 test262 tests.

Both the JSTypeFeedbackSpecializer and the JSTypeFeedbackLowering is
dead code by now, since the more general JSNativeContextSpecialization
deals with the property/global load/store type feedback in a way that
also interacts properly with inlining.

e16dd13d6d [turbofan] Add initial support for global specialization.
Introduce a new JSGlobalSpecialization advanced reducer that runs
during the initial inlining and context specialization, and specializes
the graph to the globals of the native context.  Currently we assume
that we do not inline cross native context, but long-term we will grab
the global object from the JSLoadGlobal/JSStoreGlobal feedback (with the
new global load/store ICs that are currently in the workings), and then
this whole specialization will be fully compositional even across
cross-context inlining.

Note that we cannot really handle most of the stores to global object
property cells because TurboFan doesn't have a mechanism to enforce
certain representations.  Also note that we cannot yet fully benefit
from the type feedback collected on the global object property cells,
because the type system cannot deal with maps in a reasonable way.

Defines a new --harmony-tolength flag, and a ToLengthFlagged() runtime function,
that is used where ES6 requires ToLength(), but a pre-ES6 conversion existed
before. When the flag is disabled, the function uses TO_UINT32(), which is
the pre-ES6 behaviour. When the flag enabled, the ES6-compliant ToLength()
conversion is used.

Once  a range is found to have a conflict, split around all the calls it
crosses over, since it will anyway have conflicts there, too.

Incrementally, from the last change to greedy, this change brings
overall improvement in benchmarks. In fact, except for 2 regressions
in Jetstream (splay-latency and date-format-xparb, at 6 and 7%
respectivelly), everything else is in the green or noise. Quite a few
benchmarks are over 3%, with a few (zlib, for example) in the double
digits.

71779375ad [turbofan] Re-wire greedy.
We completely un-wired the greedy allocator to focus on the
stackchecks in loops (splintering) work. This change re-wires greedy,
still behind its flag. For now, enabling the greedy allocator disables
the stackchecks in loops feature (and range splintering), so that we are
at the baseline we left it at.

The main contribution in this change is adapting the codebase after
the live range model refactoring, whereby RegisterAllocationData's
live_ranges() contains just top-level ranges, and children are accessed
via their parents.

5d954d6506 [turbofan] Deferred blocks splintering.
This change encompasses what is necessary to enable stack checks in loops without suffering large regressions.

Primarily, it consists of a new mechanism for dealing with deferred blocks by "splintering", rather than splitting, inside deferred blocks.

My initial change was splitting along deferred block boundaries, but the regression introduced by stackchecks wasn't resolved conclusively. After investigation, it appears that just splitting ranges along cold block boundaries leads to a greater opportunity for moves on the hot path, hence the suboptimal outcome.

The alternative "splinters" ranges rather than splitting them. While splitting creates 2 ranges and links them (parent-child), in contrast, splintering creates a new independent range with no parent-child relation to the original. The original range appears as if it has a liveness hole in the place of the splintered one. All thus obtained ranges are then register allocated with no change to the register allocator.

The splinters (cold blocks) do not conflict with the hot path ranges, by construction. The hot path ones have less pressure to split, because we remove a source of conflicts. After allocation, we merge the splinters back to their original ranges and continue the pipeline. We leverage the previous changes made for deferred blocks (determining where to spill, for example).

1ebf0d7c5d Split function block scoping into a separate flag
In an initial attempt to implement sloppy mode lexical bindings,
functions were made lexically scoped in sloppy mode. However, the
ES2015 spec says that they need an additional hoisted var binding,
and further, it's not clear when we'll implement that behavior
or whether it's web-compatible.

This patch splits off function block scoping into a new, separate
flag called --harmony_sloppy_function. This change will enable the
possibility of testing and shipping this feature separately from
other block scoping-related features which don't have the same risks.

With the recent changes to the incremental marking API we can now kick off
incremental marking while respecting callback flags.

Performance neutral for smoothness.image_decoding_cases on N9 (read: does not
crash) as long as we synchronously process phantom callbacks
(kGCCallbackFlagForced).

OORT single run:
  "marksweep": {
    "count": 5,
    "pause_min": 7.5,
    "pause_max": 158.8,
    "pause_avg": 97.52000000000001,

--harmony_sloppy includes behavior to turn on sloppy mode lexical
bindings. Before this patch, it also included a way to parse let
which is likely web-incompatible (let is disallowed as an
identifier). This patch splits off the let parsing from the more
general block scoping code, so that block scoping can be developed
independently.
