Bytecode compilation is not affected by whether it needs to
be serialized. Only TF-generated code objects included in the
snapshot are part of the startup snapshot. We therefore do
not need to pass the flag through the compilation info.

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.

This is necessary to be able to store the string length next to the hash field in the same 64bit word on 64bit architectures. Otherwise the forwarding pointer will overwrite the length breaking heap guarantees. ThinStrings already just do the right thing, so just use that instead.

With this CL, {CreateDefaultPlatform} returns a unique_ptr to indicate
that the caller owns the returned memory. We had several memory leaks
where the memory of the DefaultPlatform did not get deallocated.
In addition, the {TracingController} of the {DefaultPlatform} also gets
received as a unique_ptr. Thereby we document that the {DefaultPlatform}
takes ownership of the {TracingController}. Note that the memory of the
{TracingController} was already owned by the {DefaultPlatform}, but it
was not documented in the interface, and it was used incorrectly in
tests.

- Remove weak-collection.js

- 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.

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.

If there is a WeakMap in a retaining path of an object, then we have
two choices:
1) use the WeakMap backing store as the retainer.
2) use the key in the WeakMap as the retainer.
Both cases can be useful for debugging memory leaks.
This patch adds a second parameter to %DebugTrackRetainingPath().
If this parameter is "track-ephemeral-path", then the retaining path
printer will use the key in the WeakMap as a retainer. Otherwise,
the WeakMap backing store will be reported as the retainer.
