We explicitly serialize the backing store when we see the TypedArray.
We then put the reference in the external_pointer. To recalculate the
backing_store pointer during deserialization, we have to keep track of
each TypedArray and then fix up the pointer by adding the offset again.

The regexp fast path in MaybeCallFunctionAtSymbol had an issue in which
we'd call ToString after checking that the given {object} was a fast
regexp and deciding to take the fast path. This is invalid since
ToString() can call into user-controlled JS and may mutate {object}.
There's no way to place the ToString call correctly in this instance:
1 before BranchIfFastRegExp, it's a spec violation if we end up on the
slow regexp path;
2 the problem with the current location is already described above;
3 and we can't place it into the fast-path regexp builtin (e.g.
RegExpReplace) either due to the same reasons as 1.
The solution in this CL is to restrict the fast path to string
arguments only, i.e. cases where ToString would be a nop and can safely
be skipped.

This gives up on earlier attempts to interpret DeadValue as a signal of

nodes, and even pure branch nodes that use them, can get scheduled so
early that they get reachable. Instead, we now eagerly remove branches
that use DeadValue in DeadCodeElimination and replace DeadValue inputs
to value phi nodes with dummy values.

Resetting phantom handles while keeping finalizers alive leads to the
problem of eagerly resetting a handle although another finalizer keeps
it (transitively) alive.
This becomes a problem with internal pointers to Blink as without
global handle a Blink GC is free to collect wrappables.
This CL untangles finalizers handling from phantom handle resets by
introducing a separate path for resetting.

Previously StaNamedProperty and StaKeyedProperty were in a weird state where
they claimed to not touch the accumulator, but actually did in case they were
deopted in the middle. A frame was added in the middle to overwrite the
accumulator again with the right value before returning from the setter, using
a lot of complexity in the deoptimizer.
This changes those instructions to be marked as writing to the accumulator
(e.g., the result of the setter), and uses to manually store and reload into
the accumulator the value being stored.
If we want to avoid the additional bytecodes, we could make sure that bytecodes
that claim to leave the accumulator alone don't deopt back to Advance/Dispatch
but LoadAccumulatorWithValue/Advance/Dispatch. That's in a way similar to what
happened before this CL, but I believe could be implemented much simpler.

If the destination register of a binop is the same register as the
right hand side, we would first move the left hand side into that
register (overwriting the value of the rhs), and then use the rhs.
This CL fixes this issue and adds a regression test.

Fix a stack overflow in the wasm_compile_fuzzer by limiting the
recursion depth to 64. At this depth, we always just generate a
constant expression.

It is preparation step for step-into-worker. There are few changes:
- added breakOnAsyncCall flag for Debugger.stepInto. When flag is set
and async task is scheduled before step-into finished, we pause
execution with additional Debugger.paused event. This event contains
additional scheduledAsyncTaskId field.
- added Debugger.pauseOnAsyncTask. This method will pause execution as
soon as given async task is started.
This mechanism is replacement for Debugger.scheduleStepIntoAsync which
can not be used between multiple targets.
As result we can split async task scheduling in one target and
requesting break for this async task running in another target.
