The ES2015 spec is missing an extension of sloppy-mode block-scoped function behavior to the global scope in scripts, as well as to eval. This patch brings that hoisting to those two areas. The behavior is not perfectly spec-compliant since properties created on the global scope should be set as enumerable even if they are non-enumerable previously, but the attributes will not be modified if the property already exists under this patch.

ES2015 specifies very particular semantics for functions defined in blocks. In strict mode, it is simply a lexical binding scoped to that block. In sloppy mode, in addition to that lexical binding, there is a var-style binding in the outer scope, which is overwritten with the local binding when the function declaration is evaluated, *as long as* introducing ths var binding would not create a var/let conflict in the outer scope. This patch implements the semantics by introducing a DelegateStatement, which is initially filled in with the EmptyStatement and overwritten with the assignment when the scope is closed out and it can be checked that there is no conflict. This patch is tested with a new mjsunit test, and I tried staging it and running test262, finding that the tests that we have disabled due to lack of Annex B support now pass.
