Shell::SerializeValue was using a HandleScope, but was also storing Handles in
an ObjectList. The ObjectList handles would persist after the function had
returned, but will have already been destroyed by the HandleScope, so there is
a use-after-free.

This change removes the HandleScope in Shell::SerializeValue and relies on the
caller's HandleScope.

If we do not clear next links during serialization, the
serializer would simply follow those links and serialize
arbitrary objects held by weak cells. This breaks the
invariant in the code serializer, which crashes if it
sees context-dependent objects.

This way we need the common types only once per process and we don't
need to recreate them for every compilation. It uses the same pattern
that we already apply to caching operators. This simplifies the type
cache a lot.

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.
