[turbofan] Add support for extending properties backing store.

TurboFan didn't support transitioning stores that also need to grow the
properties backing store so far. This CL adds support for re-allocating
the properties backing store in-place, so these stores can participate
properly in various optimizations like escape analysis and allocation
folding.

Hey Igor,

Here's the support for inlining the properties backing store extension. It
properly integrates with escape analysis and allocation folding, and generates
perfect code in most cases.
Please take a look.

Thanks,
Benedikt
