Implemented features are:

*) Method References
Method references have been implemented using the 'infix' notation suggested by John Rose. For example, a method reference for a method m in class A is denoted as 'A#m'. Method references can include an actual argument types list (in order to disambiguate in case of overload resolution). Big thanks to John Rose, as I re-used most of the code for handling code generation of method handle literals.

*) Effectively final analysis
Local variables that are never assigned can now be referenced from a lambda body.

*) Removed explicit support for function types
The option -XDallowFunctionTypes has been removed. As a result, SAM types are the only legitimate target types for lambda expressions/method refs.

*) Miscellaneous bug fixes (thanks to Peter Levart for the feedback).

TODO:

*) break/continue/return
