Allow redeferral of functions that were fully compiled on original parse. Let the parser track heuristic and functional reasons for non-deferral separately by splitting one existing fscr bit into two. Functions that cannot be deferred for functional will not be redeferral candidates, but functions that were initially not deferred for heuristic reasons, e.g. small scripts, will become candidates for redeferral. Also fix an issue exposed by this change where FunctionInfo attribute bits set during byte code generation could be cleared in FuncInfo finalization.

[CVE-2017-11807] Prevent redeferral of functions for which we are generating byte code. The FuncInfo holds a reference to the FunctionBody, and redeferral will clean up the FunctionBody and any entry points that have been created for it, as well as pointing the FunctionInfo to a new proxy. Restore the (re-)deferral attribute on candidate functions when the ByteCodeGenerator instance is being destroyed. Also make sure that disabling the CanDefer attribute doesn't prevent generation of scope info we will need if we redefer later.

Small cleanup in byte code gen. Remove from FuncInfo the hasGlobalReference bit, which has no significant uses, and the hasCapturedThis bit, which has no uses at all.

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.
