RFR 8014133: Spliterator.OfPrimitive

[Paul Sandoz]

Hi,

Please review:

  http://cr.openjdk.java.net/~psandoz/lambda/spliterator/jdk-8014133/specdiff/overview-summary.html

This enables more sharing of primitive-based spliterator code and should also reduce the bloat of primitive-based concat spliterator implementations, if we choose to add concatenation of primitive-based streams.

Paul.
