b2348f42c0 [android] Remove legacy architecture configs from perf runner.
The android_* configs were never real v8 target
architectures, only make targets. This doesn't make sense
with ninja anymore.

5056c8219a [turbofan] Revive the useful parts of the SimplifiedOperatorReducer.
This partially reverts https://codereview.chromium.org/1162563002
because we might actually be able to optimize certain combinations
now due to dead code elimination.

733a246386 [turbofan] Proper dead code elimination as regular reducer.
The three different concerns that the ControlReducer used to deal with
are now properly separated into

  a.) DeadCodeElimination, which is a regular AdvancedReducer, that
      propagates Dead via control edges,
  b.) CommonOperatorReducer, which does strength reduction on common
      operators (i.e. Branch, Phi, and friends), and
  c.) GraphTrimming, which removes dead->live edges from the graph.

This will make it possible to run the DeadCodeElimination together with
other passes that actually introduce Dead nodes, i.e. typed lowering;
and it opens the door for general inlining without two stage fix point
iteration.

To make the DeadCodeElimination easier and more uniform, we basically
reverted the introduction of DeadValue and DeadEffect, and changed the
Dead operator to produce control, value and effect. Note however that
this is not a requirement, but merely a way to make dead propagation
easier and more uniform. We could always go back and decide to have
different Dead operators if some other change requires that.

Note that there are several additional opportunities for cleanup now,
i.e. OSR deconstruction could be a regular reducer now, and we don't
need to use TheHole as dead value marker in the GraphReducer. And we can
actually run the dead code elimination together with the other passes
instead of using separate passes over the graph.  We will do this in
follow up CLs.

80a6e53935 [turbofan] Move graph trimming functionality to dedicated GraphTrimmer.
Up until now that was still mixed with control reduction in the
ControlReducer. This separation allows us to remove the horrible
Reducer::Finish hack and also do graph trimming at more appropriate
places in the pipeline (i.e. trim dead nodes after generic lowering,
which can also make nodes dead).

4e0b7b0cf5 Separated the new register allocator in its own files.
Opportunistically removed GreedyAllocator::TryReuseSpillForPhi because it is actually unsuitable for Greedy. It was copied from Linear and it relies on hints, however, the current implementation of hints assumes linear scan.

This change doesn't aim to address performance nor correctness for Greedy.

fbe973ff17 [test] Refactoring - Use subject/observer pattern for progress indicators.
This should prevent bugs caused by missing super calls in
overridden methods. The assumption is that methods of
different indicators are independent.

e59e40a354 Implement Atomics API
This is behind the flag "--harmony-atomics", and it only works on
SharedArrayBuffers. This implementation only includes the runtime functions.
The TurboFan implementation will be next.

e2e47f30be [turbofan] First step towards sanitizing for-in and making it optimizable.
In a nutshell: The FILTER_KEY builtin is gone, and was replaced by a
simple runtime call to ForInFilter, which does everything and is even
cheaper (because FILTER_KEY used to call into the runtime anyway).
And ForInFilter returns either the name or undefined, which makes it
possible to remove the control flow construction from the AstGraphBuilder,
and thereby make both the initialization and the per-loop code of for-in
optimizable later (in typed lowering).

This adds a new external type (v8::SharedArrayBuffer) that uses a JSArrayBuffer
under the hood. It can be distinguished from an ArrayBuffer by the newly-added
is_shared() bit.

Currently there is no difference in functionality between a SharedArrayBuffer
and an ArrayBuffer. However, a future CL will add the Atomics API, which is
only available on an SharedArrayBuffer. All non-atomic accesses are identical
to ArrayBuffer accesses.

570fca61fc Re-land: Make V8 extras a separate type of native
Instead of making them an extra option that gets passed in and compiled
at the end of the natives file for a given run of js2c, we now make them a
separate run of js2c with a separate natives file output.

This natives file output is then compiled in the bootstrapper. It is not part
of the snapshot (yet), but instead is treated similar to the experimental
natives, just without any of the complexity that comes from tieing the
behavior to flags. We also don't need counterparts to
InitializeExperimentalGlobal and InstallExperimentalNativeFunctions (yet?).

This fixes the issue with https://codereview.chromium.org/1129743003 by making
the dummy file that is generated for snapshots with no extras (or no experimental
features) nonempty.

d21de2a48b [turbofan] Fix tail call optimization.
Tail calls are matched on the graph, with a dedicated tail call
optimization that is actually testable. The instruction selection can
still fall back to a regular if the platform constraints don't allow to
emit a tail call (i.e. the return locations of caller and callee differ
or the callee takes non-register parameters, which is a restriction that
will be removed in the future).

Also explicitly limit tail call optimization to stubs for now and drop
the global flag.
