      Split off a separate --harmony_sloppy_let flag · 2d2b72f6
      littledan authored
      --harmony_sloppy includes behavior to turn on sloppy mode lexical
      bindings. Before this patch, it also included a way to parse let
      which is likely web-incompatible (let is disallowed as an
      identifier). This patch splits off the let parsing from the more
      general block scoping code, so that block scoping can be developed
      independently.

      Introduce extended mode. · 1e9a7267
      keuchel@chromium.org authored
      This CL introduces a third mode next to the non-strict
      (henceforth called 'classic mode') and 'strict mode'
      which is called 'extended mode' as in the current
      ES.next specification drafts. The extended mode is based on
      the 'strict mode' and adds new functionality to it. This
      means that most of the semantics of these two modes
      coincide.
      
      The 'extended mode' is entered instead of the 'strict mode'
      during parsing when using the 'strict mode' directive
      "use strict" and when the the harmony-scoping flag is
      active. This should be changed once it is fully specified how the 'extended mode' is entered.
      
      This change introduces a new 3 valued enum LanguageMode
      (see globals.h) corresponding to the modes which is mostly
      used by the frontend code. This includes the following
      components:
      * (Pre)Parser
      * Compiler
      * SharedFunctionInfo, Scope and ScopeInfo
      * runtime functions: StoreContextSlot,
        ResolvePossiblyDirectEval, InitializeVarGlobal,
        DeclareGlobals
      
      The old enum StrictModeFlag is still used in the backend
      when the distinction between the 'strict mode' and the 'extended mode' does not matter. This includes:
      * SetProperty runtime function, Delete builtin
      * StoreIC and KeyedStoreIC
      * StubCache
