We have a bottleneck around storing elements in the array and object prototypes,
but the Push() and Unshift() builtins don't respect them.

Fix this exactly to the level of existing support for stores.

The embedder has to take appropriate steps to ensure that the
ArrayBuffer doesn't die while it's accessing the pointer, e.g. keep a
Local handle to it around

External strings are serialized as internal strings. The current way
of collecting stats is slightly wrong. We ought to use the map and
size passed to SerializePrologue.

This adds a stripped down version of the SQLite benchmark (running with
--size 1) to the mjsunit suite. We might want to move that to a
dedicated slow/stress/whatever test suite once an appropriate decision
is made.

This is first step towards adding V8 heap statistics to the memory
tracing infrastructure. For being able to get useful memory number into
the memory dump, v8 needs to provide an external api needs to obtain
more information about the heap. So, this Cl extends the api to give
information about the memory allocated and used in the spaces.
