hg: lambda/lambda/langtools: Improved support for lambda conversion.

[Neal Gafter]

Maurizio-

What are the rules about checked exceptions thrown by the constructor?  What accessibility rules are enforced for the constructor?  How are the constructor's type parameters inferred?  Is there any way to access the SAM class from within the lambda?

> Now the prototype supports lambda conversion where the target type is an abstract class. This is (temporarily) done by generating a synthetic anonymous inner class implementing the SAM method. Also added some checks involving lambda conversion described in the strawman:
