There are a same name field equivalence_id_ in both
BytecodeRegisterOptimizer and RegisterInfo, but one of them is int,
another one is uint32_t, it's better to change them as same type
to avoid addtional or potential type casting.

Factory::CopyCode was using ProcessBlackAllocatedObject and
WriteBarrierForCode(Code) to handle write barriers for that newly
created code object. But even when used in tandem with each other they
would miss OLD_TO_NEW references in the code object header.

This CL simplifies Factory::CopyCode by letting
WriteBarrierForCode(Code) handle all outgoing pointers of that code
object (not just a subset of RelocInfos) by implementing an
ObjectVisitor. This removes the need for ProcessBlackAllocatedObject.

Since Factory::CopyCode was the only user of
ProcessBlackAllocatedObject, we can also remove all the object
revisiting logic in the main thread marker.

While it is not required to invoke the full barrier in this case, we
can invoke the full write barrier which improves verification but also
makes the code easier to understand by relying less on GC

When calculating the GC collection rate, we assume that the start object
size (before GC) is non zero. It appears that this is not always the
case, not only because of tests that explicitly trigger GC, but also in
Chrome, when the --gc-interval flag is used with a small interval value.

Furthermore, efficiency calculation (freed bytes over GC duration)
assumes that the duration of the GC is non zero. However, if the clock
resolution is not small enough and the entire GC is very short, the
timed value appears to be zero. This again leads to NaN values showing
in metrics and CHECKs failing and has already been fixed for Oilpan
(crrev.com/c/3723499).

This CL fixes these two issues.

It introduces GetSecondReturnedValue node, which must be added
immediately after a node that calls a builtin that expects 2
returned values.

It simply binds kReturnRegister1 to a value node. Since the previous
node must have been a builtin call, kReturnRegister1 is free in
the register allocator. No gap moves will be emitted between these
two nodes.

This is a reland of commit 4bab7a8e

The reland changes the way how we install the async stack tagging API
on the console object. Instead of using `v8::Object::Set`, we use
`createDataProperty` which is sufficient. With `Set`, arbitrary
JS could run via accessors, which might not be allowed depending on
when the API is installed.

v8::TracedReference is supposed to be used from objects allocated on
CppHeap. Such objects can be in construction during garbage
collection, meaning that they are unable to invoke
Trace(v8::TraceReference) as they have not been properly set up.

It is thus necessary to use conservative tracing to find
v8::TracedReference (backed by TracedNode in GlobalHandle) in
in-construction objects.

With the new API:

With streaming compilation we delay the generation of errors until after
all bytes are received, so that potentially better error messages get
generated. With this CL we also delay the generation of errors in the
combination of lazy compilation and streaming compilation.

In particular, this CL does the following:
* It avoids the creation of a `DecodeFail` task in
`FinishAsyncCompileJobWithError`, which would create an error immediately before a potential name section arrived.
* It calls `CompilationStateImpl::SetError()` so that an error is
created once the stream finishes.
* It removes the return value of `ProcessFunctionBody` so that wire
bytes continue to be received even after a validation error.
* It adds an early exit to `ProcessFunctionBody` if
`CompilationStateImpl::failed()` is true, so that we don't continue
validation after the first detected error.

If DefaultJobState::Join is called before any worker tasks were spawned
(e.g. right after Platform::CreateJob), it should spawn the required
number of worker tasks (mimicing what Platform::PostJob followed by Join
would do, but with less context switches).
This fixes regressions we got from switching from Platform::PostJob to
Platform::CreateJob.
