[8u60] Request for Approval to Backport: JDK-8069545: javac, shouldn't check nested stuck lambdas during overload resolution

[Srikanth]

Greetings,

Please approve the backport this fix made for JDK9:

JDK9 bug: https://bugs.openjdk.java.net/browse/JDK-8069545
JDK9 HG change log: 
http://hg.openjdk.java.net/jdk9/dev/langtools/rev/b93a15ac3bde
JDK8 backport ticket: https://bugs.openjdk.java.net/browse/JDK-8069546

The same patch applies cleanly and langtools + compiler JCK tests are clean.

TIA,
Srikanth
