[CVE-2017-8740] Fix bad byte code gen for 'with'. The original (conservative) fix for this issue relied on marking scopes as containing 'with'. But because block scopes are created lazily, we can miss the opportunity to mark a scope. Instead, implementing a more accurate fix that marks symbols that are referenced from within 'with' statements as needing scope objects if they are closure-captured.

Fix bad byte code when block-scoped function is called from with. Yesterday's fix was incomplete, because it failed to address the case in which the nested function called from a with statement is declared in a lexical scope. The concept we're conservatively using, of a scope containing a with statement as well as closure-captured data, has to be tracked on individual scopes rather than functions.

Defer functions enclosed in all contexts. Support deferral of functions enclosed in scopes other than function body and function expression scope -- in particular, ES6-style lexical scopes and parameter scopes. This requires changing ScopeInfo so that it is associated with a single scope rather than a function body. Instead of carrying per-function information for body/var scope, parameter scope, and function expression scope, ScopeInfo will describe one scope, with a value identifying the scope type, a pointer to the FunctionInfo that contains it, and a pointer to the enclosing ScopeInfo.. A FunctionProxy will point to the ScopeInfo that is the nearest enclosing scope. At parse time, we will reconstitute the closure environment by walking the list of enclosing ScopeInfo's. The code that allowed redeferral to work around the context limitation of deferring parsing is deleted, and the OptimizeBlockScope feature is off by default, as it doesn't play well with this new logic and isn't required to make (re-)deferral effective. (We will want to revisit it.)

Let redeferral work around block scope limitation of deferred parsing. Detect cases where only block-scoping prevents upfront deferral. Also detect cases where it is safe to treat a lexically-scoped function as a var-scoped one. For functions that meet both criteria, use the var binding for it in place of the lexical binding. If at byte code gen time there are no lexical/with/catch scopes in the current chain, mark the function as a redeferral candidate.

Remove ParserBind phase switch and related dead code. The redeferral work makes this path too much of a headache to maintain, so we should cut it loose now.

Remove invalid assert. Inner scope enumeration can happen multiple times if we re-visit the AST during byte code gen. The re-enumeration is valid, so just let it happen.
