This adds a non-standard, unsafe instruction for performance
experiments: ref.cast_nop_static behaves like ref.cast_static
as far as static types are concerned, but emits no code.

The issue is that a thread_local variable used in RwxMemoryWriteScope
can't be directly accessed from another component, so the workaround is
to avoid inlining accesses the variable into other components.

This filters the flags --maglev and --no-use-map-space when passed to
foozzie. Most open bugs are known or spurious, but all take up the
limited hashes for correctness bugs, which prevents finding other
bugs. Filtering on the source-side will make those reports appear
as fixed.

Doc: https://bit.ly/revive-restart-frame

This CL implements support for the Debugger's "restart frame"
functionality in the deoptimizer. When the debugger wants to restart
a frame, we throw a termination exception.

If the restarted frame is an optimized frame or was inlined into
an optimized frame, the deoptimizer has to materialize all the
frames up to (and including) the frame we want to restart. This
is similar to materializing all the frames up until the frame
with a catch handler.

The main difference is that we do not jump into the middle of the
top-most materialized frame, but instead use the
RestartFrameTrampolone to immediatly exit, and then re-invoke the
top-most materialized frame.

We were also restting the parameter which would read the internal

used for v8::TracedReference.

Since we now promote all young objects into old space on full GCs, we
don't need to sweep pages for iterability anymore in new space.

Minor MC doesn't need to make a page iterable when promoting the full
page into the new space. This is because maps are not reclaimed during

This CL implements support for the Debugger's "restart frame"
functionality in the unwinder. When the debugger wants to restart
a frame, we throw a termination exception. The unwinder checks if we
are currently in "restart frame mode", and if so, drops execution
into a special builtin instead of trying to find a catch handler.

Optimized frames are handled similarly, but the deoptimizer has to
materialize the frames first before also dropping into the
special builtin.

Drive-by: Rename `ShouldRestartFrame` to `IsRestartFrameScheduled`, so
we can reuse the name `ShouldRestartFrame` as a query method to check
if a specific frame is the frame we want to restart.

Avoid zapping freed memory in NotifyObjectSizeChange. This fixes the
linked performance regression introduced with
https://crrrev.com/c/3607992. Beginning with that CL we would always
zap freed memory on the main thread, while previously we only did this
in CreateFillerForArray when the FixedArray could actually contain
references.

While we could restore the previous behaviour as well, we simply stop
zapping freed memory in NotifyObjectSizeChange altogether for better
