Review request for JDK- 8006220 Faster creation of properties

[Marcus Lagergren]

Given that you have verified that benchmark performance has no regressions, I think this is a great step in the direction we want to go. Less complexity and the possibility to type change spill properties similar to what dual fields already does.

+1 on the condition that performance hasn't regressed.

The most significant changes here are the introduction of slot to basic properties, elimination of embedded fields and the elimination of SpillProperties (merged with AccessorProperty.)
