d8981833eb reland: [heap] Concurrently free ArrayBuffer allocations.
Free ArrayBuffer backing stores on a background thread, rather than
blocking the main thread after processing. Could potentially cause
contention with the array buffer allocator once JS execution resumes.

The new ArrayBufferCollector class tracks these dead allocations.

Later, the processing of array buffers can happen in parallel.

3bedee6895 [build] Exclude nosnap targets on nosnap builds
When using ninja to build without specifying explicit targets,
all existing targets in any BUILD.gn file are built/executed.

We now hide the snapshot targets behind the snapshot condition
to prevent them from being built and executed in nosnap builds.

977da55033 [bigint] Encapsulate internals in MutableBigInt
This CL creates the invariant that the BigInt class treats
BigInt objects as immutable. Writing to new BigInt objects
as part of their construction is done by the MutableBigInt
helper class, which in turn is hidden as an implementation
detail in bigint.cc.
As a side effect, this refactoring enforces right-trimming
checks for all newly created BigInts, and ensures that all
BigInt allocations possibly exceeding kMaxLength check for
this case and throw a RangeError instead of crashing.

8de2e6db02 [platform] Implement TaskRunners in the DefaultPlatform
This CL implements the TaskRunners in the DefaultPlatform which has been
added recently to the platform API. In addition I changed how task
posting works on the DefaultPlatform.

With this implementation the DefaultPlatform keeps one
DefaultForegroundTaskRunner per isolate, plus one
DefaultBackgroundTaskRunner. The DefaultPlatform owns these TaskRunners
with a shared_ptr, which is also shared with any caller of
GetForegroundTaskRunner or GetBackgroundTaskrunner.

This CL moves the task management from the DefaultPlatform to the
TaskRunners.  The DefaultForegroundTaskRunner owns and manages the the
task queue, the delayed task  queue, and the idle task queue. The
DefaultBackgroundTaskRunner owns the WorkerThread pool and the
background task queue.

In addition changed many Task* to std::unique_ptr<Task> to document task
ownership.

c5c50e1860 [builtins] Port WeakMap/WeakSet constructor to CSA
- Remove weak-collection.js
- Adds TFJ builtins for WeakSet and WeakMap constructors
- Unified helpers and constructor behavior into a BaseCollectionsAssembler
- Fast paths for...
  - unmodified constructor function
  - argument is a fast JS array
  - entries are fast JS arrays, for Map/WeakMap
  - no arguments passed

Quick benchmarks shows significant improvements (1.12x - 5.7x!) for ALL collection constructors (weak and non-weak):
https://github.com/peterwmwong/v8-perf/blob/master/weakcollection-constructor/README.md

More could be done for performance.  Currently we always call out to JS to add entries, if we knew the prototype was unmodified, we could call the builtins directly.

18cac20c50 [parser] Greatly simplify Array spread rewriting code
Since each Array literal containing a spread is individually queued for
rewriting, there's no need for an AstVisitor here: a simple linear
pass through the queue is sufficient.

This patch deletes AstExpressionRewriter and all the machinery supporting
it in the AST. This code was built with the idea of using it as
a general expression rewriting mechanism in the parser, but those use
cases never materialized, and Array spread remains the only thing
that used this code.

metadata. I96a8a7cdded6f7c37b6f1da659d63df9e3a5de2b moved
the Code class to a new file without updating the postmortem

1b2a341e02 [snapshot] Move bytecode handlers to builtins snapshot
This is the first step towards lazy-deserializing bytecode handlers.

Bytecode handler code objects are now serialized into the builtins
snapshot area (which, like many other related concepts, has become
somewhat of a misnomer now that it contains both builtins and
handlers).

Handlers are still eagerly-deserialized upon Isolate creation. This will
change in follow-up CLs.

98e26799ec [foozzie] Fix architecture auto-detect with multi-arch builds
The current_cpu value was erroneously removed from the build config json.
In multi-arch builds, each toolchain subdirectory in the build-product
output emits its own build-config json, where current_cpu determines
the architecture type of the sub-build.

Correctness-fuzzer runs could wrongly determined x86 sub-builds as x64.

a74da81808 s390: Liftoff: a baseline compiler for WebAssembly
Port 266e803ea9

Original Commit Message:
  This CL adds a first implementation of Liftoff, the new wasm baseline
  compiler, for x64 and ia32. It currently supports the most important
  i32 instructions and control instructions. Whenever it encounters an
  instruction it does not support yet, it aborts.
  In a subsequent CL, Liftoff will be called from the
  WasmCompilationUnit, falling back to Turbofan compilation if the
  baseline compiler bails out.

4213af64b6 [es2015] Optimize Reflect.has builtin.
Port the baseline version of Reflect.has to the CodeStubAssembler and
reuse the existing logic for HasProperty (i.e. the HasProperty builtin).
Also inline the Reflect.has builtin into TurboFan, by adding a check
on the target in front of a use of the JSHasProperty operator.
Technically this additional check is not necessary, because the
JSHasProperty operator already throws if the target is not a JSReceiver,
but the exception message is confusing then.

This improves the performance of the micro-benchmark from

  reflectHasPresent: 337 ms.
  reflectHasAbsent: 472 ms.

to

  reflectHasPresent: 121 ms.
  reflectHasAbsent: 216 ms.

which is a nice 2.8x improvement in the best case. It also improves the
chai test on the web-tooling-benchmark by around 1-2%, which is roughly
the expected win (since Reflect.has overall accounts for around 3-4%).
