Review request for JDK- 8006220 Faster creation of properties

[Hannes Wallnoefer]

I like the direction of this patch.

One problem I see is that the modifiable flags field is used for 
calculating the hash code of PropertyMap. Also "fieldMaximum" is 
mistyped as "fieldMaxiumum" three times in PropertyMap and MapCreator.

Apart from these the patch looks good to me.

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.)
