hg: lambda/lambda/langtools: Handle non-static method references from static context. More specifically, if f is an instance method of Z whose signature is A, B->C, then #obj.f is of type A, B->C and #Z.f is of type Z, A, B->C.

Brian-

Project lambda hasn't specified the behavior of the conversion (i.e., when
are exceptions from the SAM constructor thrown), so it's hard to know what
to want from jsr292.  Perhaps now would be a good time to specify the
desired behavior and see if jsr292 can deliver it.
