[8u-60] request for approval to backport JDK-8079613: Deeply chained expressions + several overloads + unnecessary inference result in excessive compile times.

[Jan Lahoda]

Hello,

I'd like to ask for an approval to backport the following fix to 8u-dev:

Bug: https://bugs.openjdk.java.net/browse/JDK-8079613
jdk9 fix: http://hg.openjdk.java.net/jdk9/dev/langtools/rev/b5be088d41c7

The fix applies cleanly to 8u-dev/langtools after unshuffling.

Thanks,
     Jan
