MarkingWorklistHolder has two references to the shared marking worklist:
1) as a standalone worklist for general marking,
2) as a context worklist for per-context mode marking.

Because of that the shared worklist gets updated twice and breaks
the invariants of UpdateMarkingWorklistAfterScavenge.

This patch adds a new BackingStore::Reallocate function that internally
uses a new ArrayBuffer::Allocator::Reallocate provided by the embedder.

The default implementation of the function simply copies the backing
store. The embedder can override the function and provide a more
efficient implementation e.g. using realloc.

Remove AstConsString "internalization", and instead make the conversion
to heap String be on-demand with an Allocate method. We never actually
need the heapified cons string more than once, so there's no need to do
the internalization walk or do the next/string union dance in the
AstConsString class.

This also allows us to specify how we want to allocate the String at the
call site. In particular, it allows us to allocate a flat SeqString rather
rather than a ConsString. This allows us to avoid allocating ConsStrings
which will just be passed to a flatten call, and especially avoid
allocating dead ConsStrings in the off-thread old space.

'resumed' events are sent to the renderer from V8 and stored in a queue.
We didn't flush this queue previously, meaning these events would sit in
the queue until another message coincidentally flushed the queue.

Under some circumstances, the resumed event would not get flushed and
the UI would still be in a paused state, even when JS had resumed.

  we hit a stop or a bkpt instruction or else we'll end up in an

- The "break" and the "stop unstop" command write into code space, so
  they need to temporarily make code space writable or else they
  just crash. (Note that this doesn't work for embedded builtins.)

Lowers the call descriptor of a wasm function if it contains simd.

Also fixes a couple of issues with the lowering of kParameter:
- the old_index == new_index check is incorrect, it would only work if
the s128 parameter is the first parameter
- the old_index was also not adjusted to account for Parameter[0] being
the wasm instance object
- new_index needs to be adjusted to account for the instance object too

These fixes make it more similar to the lowering of kParameter in
int64-lowering.c.

Also add a new mjsunit test to exercise this logic.

Bumping the max TypedArray length caused the typer to make different
representation decisions, which caused inefficient back-and-forth
conversions. This patch repairs the microbenchmark where this was
most significant.
There might be additional future work to ensure that TypedArray
accesses that actually use huge indices remain on the fast path as well.

In the case of function names, we allocate ConsStrings only to flatten
them during finalization. Allocating these ConsStrings in old space
appears to have regressed some benchmarks (especially memory benchmarks),
but is necessary for off-thread allocation which doesn't have a young
space.

Ideally, we would avoid allocating these ConsStrings in the first place,
and would flatten the data directly from the AstConsString. For now, we
make them allocate in old space for off-thread allocation only, to
revert the regressions. In the future we can investigate smarter
flattening.
