Vector ICs: Like megamorphic keyed koads, use a dummy vector for stores

It's useful for the megamorphic keyed store case to not require a
vector and slot as input. Analogous to the load case, we have a dummy
one-ic-slot vector to aid. Since the only kind of MISS is for
megamorphic cache stub failures, we don't need the real vector.
The reason is that megamorphic cache stub failures don't result in any

Reland r21101: "ARM64: use jssp for stack slots"

The original implementation assumed that LPushArguments and
LInvoke/Call* could be assumed to be exclusively sequential. However,
this isn't always the case. For example, GenerateCallFunction pushes
some arguments and then selects between HInvokeFunction and
HCallFunction.

This fixed implementation resets a pushed_arguments_ counter based on
the argument_count() of the preceeding basic block, then tracks it
per-instruction as before (except that now we maintain a count rather
than a boolean flag).

At the same time, since we now track exactly how many arguments have
been pushed onto the stack, I was able to adjust the offset accordingly
and use jssp for stack slots even when arguments have been pushed.

Add d8 API for spawning function on a new thread (Third try)

This API closely matches the Worker API. The differences:

1) The argument to the Worker constructor is a function to run, not a script.
2) Receiving a message from a worker is a synchronous API (as there is no event
loop).

The serialization done here is not robust as the real DOM implementation. For
example, recursive data structures or otherwise duplicated objects are not
allowed.

that is required to meet the IC requirements at runtime. This will allow
us to for example use feedback from a different context or divide the
