type-annotations on lambda expression

[Werner Dietl]

Maurizio, Steve, all,

please find my first (working) shot at implementing type annotations
on/within lambda expressions here:

http://hg.openjdk.java.net/type-annotations/type-annotations/langtools/rev/3508f941a8d2

I only have rudimentary tests and manually inspected a few more test
cases to see that the type annotations end up on the right symbols.

As mentioned previously, it would be great if Steve/SQE could add more
comprehensive test cases for this.

Please do let me know if you see any problem with this!

Thanks,
cu, WMD.
