> [builtins] Clean up the use of class_name / ES5 [[Class]]
>
> Before ES2015, the ES spec had a [[Class]] internal slot for all
> objects, which Object.prototype.toString() would use to figure the
> returned string. Post-ES2015, the [[Class]] slot was removed in spec for
> all objects, with the @@toStringTag well-known symbol the proper way to
> change Object.prototype.toString() output.
>
> At the time, spec-identical handling without the use of [[Class]] was
> implemented in V8 for all objects other than API objects, where issues
> with the Web IDL spec [1] prevented Blink, and hence V8, to totally
> migrate to @@toStringTag. However, since 2016 [2] Blink has been setting
> @@toStringTag on API class prototypes to manage the
> Object.prototype.toString() output, so the legacy [[Class]] handling in
> V8 has not been necessary for the past couple of years.
>
> This CL removes the remaining legacy [[Class]] handling in
> Object.prototype.toString(), JSReceiver::class_name(), and
> GetConstructorName(). However, it does not remove the class_name field
> in FunctionTemplateInfo, as it is still used for the `name` property of
> created functions.
>
> This CL also cleans up other places in the codebase that still reference
> [[Class]].
>
> This change should have minimal impact on web-compatibility. For the
> change to be observable, a script must do one of the following:
>
> 1. delete APIConstructor.prototype[Symbol.toStringTag];
> 2. Object.setPrototypeOf(apiObject, somethingElse);
>
> Before this CL, these changes will not change the apiObject.toString()
> output. But after this CL, they will make apiObject.toString() show
> "[object Object]" (in the first case) or the @@toStringTag of the other
> prototype (in the latter case).
>
> However, both are deemed unlikely. @@toStringTag is not well-known
> feature of JavaScript, nor does it get tampered much on API
> constructors. In the second case, setting the prototype of an API object
> would effectly render the object useless, as all its methods (including
> property getters/setters) would no longer be accessible.
>
> Currently, @@toStringTag-based API object branding is not yet
> implemented by other browsers. This V8 bug in particular has been an

Currently, there is no indication of memory pressure after merging pages
from off-thread space into the heap. This can mean that with lots of
off-thread compilations, we eventually run out of pages in the memory
allocator.
Now, trigger a critical memory pressure notification after merging if
the old generation is close to being unexpandable. We may want to add
other heuristics here (e.g. moderate memory pressure if the heap is
highly fragmented), or possibly add similar checks when the off-thread
space is initialized, but this works for now.
As a drive-by, inline the NotifyOffThreadSpaceMerged call into the
off-thread factory merge -- we already do a bunch of special merging
stuff in there, and nowhere else, so we may as well be explicit in what
we're actually doing. This also allows us to do a pre-check on old-space
size and hard limits just before the merge.

This reverts commit 29c1eab92e.
Reason for revert: Causes Blink test failures:
https://ci.chromium.org/p/v8/builders/ci/V8%20Blink%20Linux/4222
Original change's description:
> [builtins] Clean up the use of class_name / ES5 [[Class]]
>
> Before ES2015, the ES spec had a [[Class]] internal slot for all
> objects, which Object.prototype.toString() would use to figure the
> returned string. Post-ES2015, the [[Class]] slot was removed in spec for
> all objects, with the @@toStringTag well-known symbol the proper way to
> change Object.prototype.toString() output.
>
> At the time, spec-identical handling without the use of [[Class]] was
> implemented in V8 for all objects other than API objects, where issues
> with the Web IDL spec [1] prevented Blink, and hence V8, to totally
> migrate to @@toStringTag. However, since 2016 [2] Blink has been setting
> @@toStringTag on API class prototypes to manage the
> Object.prototype.toString() output, so the legacy [[Class]] handling in
> V8 has not been necessary for the past couple of years.
>
> This CL removes the remaining legacy [[Class]] handling in
> Object.prototype.toString(), JSReceiver::class_name(), and
> GetConstructorName(). However, it does not remove the class_name field
> in FunctionTemplateInfo, as it is still used for the `name` property of
> created functions.
>
> This CL also cleans up other places in the codebase that still reference
> [[Class]].
>
> This change should have minimal impact on web-compatibility. For the
> change to be observable, a script must do one of the following:
>
> 1. delete APIConstructor.prototype[Symbol.toStringTag];
> 2. Object.setPrototypeOf(apiObject, somethingElse);
>
> Before this CL, these changes will not change the apiObject.toString()
> output. But after this CL, they will make apiObject.toString() show
> "[object Object]" (in the first case) or the @@toStringTag of the other
> prototype (in the latter case).
>
> However, both are deemed unlikely. @@toStringTag is not well-known
> feature of JavaScript, nor does it get tampered much on API
> constructors. In the second case, setting the prototype of an API object
> would effectly render the object useless, as all its methods (including
> property getters/setters) would no longer be accessible.
>
> Currently, @@toStringTag-based API object branding is not yet
> implemented by other browsers. This V8 bug in particular has been an
> impediment to standardizing toString behavior. Fixing this bug will
> unblock [3] and lead to a better Web IDL spec, and better toString()
> compatibility for all.

Original change's description:
> [offthread] Move stress-background-compile to compiler.cc
>
> Make --stress-background-compile a V8 flag rather than a d8 flag, so
> that it also tests unittests/cctests.
>
> Now, with this flag, every top-level script compile (that fulfills a
> couple of restrictions) will be both main-thread and background-thread
> compiled, taking the result of the background compile. In the future,
> we'll probably want to verify that the two results are equivalent.
>
> One of the necessary changes to allow tests to pass was to introduce a
> concept of a "temporary" script (with a temporary script id), which
> doesn't get added to the script list. This is to avoid the main-thread
> compile part of the stress-test having a debugger-visible side-effect,
> e.g. in tests that enumerate scripts. We can't just create new ids for
> such scripts, as then script-id expectation files no longer match.

We don't use StatsCounters anymore for heap work, and this particular
counter causes issues for OffThreadSpace, as it can trigger a
non-thread-safe counter callback.
We could instead make this a thread-safe counter, but since it's unused
we may as well just remove it entirely.

Introduce an OffThreadTransferHandle (and OffThreadTransferMaybeHandle),
which points to a piece of storage known to (and owned by) the
OffThreadIsolate. On Publish, the OffThreadIsolate converts this storage
stub from a raw pointer to an off-thread object into a main-thread
Handle.
This allows users of an OffThreadIsolate to not have to worry (as much)
about the dance of saving raw object pointers before off-thread finishes
and converting those to Handles before it off-thread isolate is
published.
