Reviewed by Oliver Hunt.

Sped up property access for array.length and string.length by adding a
mechanism for returning a temporary value directly instead of returning
a pointer to a function that retrieves the value.

Also removed some unused cruft from PropertySlot.

SunSpider says 0.5% - 1.2% faster.

NOTE: This optimization is not a good idea in general, because it's
actually a pessimization in the case of resolve for assignment,
and it may get in the way of other optimizations in the future.
