RFR: JDK-8240998: Implement javac changes for deconstruction patterns.

[Jan Lahoda]

Hi,

Turned out the patch had two bugs - one related to the owners of the 
temporary variables created, which then broke type annotations; and 
another that broken de-duplication. I am deeply sorry for that. An 
updated webrev is here:
http://cr.openjdk.java.net/~jlahoda/8240998/webrev.01/

A delta from previous round:
http://cr.openjdk.java.net/~jlahoda/8240998/webrev.delta.00.01/

I am sorry for any inconvenience.
