Re-enable the V8 compilation cache on Android. This adds more memory
pressure so should only be enabled on Droid or better devices.

See http://code.google.com/p/v8/issues/detail?id=458 for an interesting
discussion on the tradeoffs between the RAM usage and performance.

This change is intended to be tested by the page cycler.
