Review request for OPENJDK6-35: backport of JDK-6650759 to openjdk6

[Ivan Krylov]

Hello,

please review the fix for OPENJDK6-35: backport of JDK-6650759 to openjdk6
Inference of formal type parameter (unused in formal parameters) is not 
performed

The changes are the same as for OpenJDK7 however hg import failed due to 
differences in the context of code being changed.

bug https://java.net/jira/browse/OPENJDK6-35
JDK bug : https://bugs.openjdk.java.net/browse/JDK-8047379
webrev http://cr.openjdk.java.net/~ikrylov/openjdk6-bug35.langtools/

Testing: build on Windows (cross-platform code, should be ok for linux 
too), all regression tests for javac - generics.

Thank you,
Ivan

PS Funny that I can not "work" ob bugs like 
https://java.net/jira/browse/OPENJDK6-35. Hence - I can not close them.

PPS In my previous request for review (for bug34) the synopsis was 
incorrect. It should have been
"Inference with wildcard types causes selection of inapplicable method "
