Updated compiler implementation as per latest spec draft (v0.4.1)
*) Lambda parameters are not allowed to shadow locals in the enclosing scope anymore.
Cleanup/improvements
*) Simplified logic for lambda attribution environment creation in Attr.java
*) Removed redundant flags in Flags.java
*) Simplified lambda AST node
*) Convert LambdaToInnerTranslator to a 'true' lambda/reference to inner class translator - i.e. so that it does not use ProxyHelper for method reference translation
*) Removed '-XDuseIndy'/'-XDuseProxy' options - now indy is the default choice when -XDlambdaToMethod is selected
*) Move code shared by both translators in the base class LambdaTranslator - now both translator share the same two-phase translation strategy (one step for analyzing lambdas/mrefs, one step for actual translation)
*) Cleanup Gen.java (all method references are now completely desugared when we get to code generation - no need to support bytecode translation for method references)
