Expressions in class heritage position do not have access to the
inheriting class's private names, only its lexical bindings. The parser
currently uses the same scope chain for both.
This CL makes scopes in class heritage position skip their outer class
when resolving private names. Whether a scope needs to skip is kept as a
bit on various scope-related data structures.

In order to reflect web reality, TC39 has made some slight changes to
name descriptors, see https://github.com/tc39/ecma262/pull/1490 for

Previously, this was run as a microtask and this CL changes it to run
as a separate task as mandated by the current WeakRef spec.
This CL also introduces a FinalizationGroup type to the V8 API
representing the JSFinalizationGroup. This has a `Cleanup`
function that runs the cleanup callback associated with it.
SetHostCleanupFinalizationGroupCallback is added to set
the embedder defined HostCleanupFinalizationGroupCallback.
ClearKeptObject is exposed on the v8::Isolate to reset the strongly
held set of objects.
The general workflow is the following:
(a) When the GC notices that a given finalization group has dirty
cells, it calls HostCleanupFinalizationGroupCallback with the given
finalization group.
(b) As part of HostCleanupFinalizationGroupCallback, the embedder
enqueues a task that at some point later calls
FinalizationGroup::Cleanup.
(c) At some point in the future, FinalizationGroup::Cleanup is called,
which runs the cleanup callback of the finalization group.
This patch also includes d8 changes to use these new APIs. Currently,
d8 cycles through the enqueued finalization groups after a synchronous
turn (and it's microtask checkpoint) and runs the cleanup callbacks.

The backtracking stack (which is actually a generic stack) used to be
statically sized. At 10k elements, it was fairly large, but still easy
to overflow on large subject strings. This CL changes it to a
std::vector-based implementation instead which grows on-demand.
Drive-by: Add braces to the BYTECODE cases to make clang-format
produce a nicer output.
