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 Review URL: http://codereview.chromium.org/8417035 git-svn-id: http://v8.googlecode.com/svn/branches/bleeding_edge@10062 ce2b1a6d-e550-0410-aec6-3dcde31c8c00

This implements block scoped 'const' declared variables in harmony mode. They have a temporal dead zone semantics similar to 'let' bindings, i.e. accessing uninitialized 'const' bindings in throws a ReferenceError. As for 'let' bindings, the semantics of 'const' bindings in global scope is not correctly implemented yet. Furthermore assignments to 'const's are silently ignored. Another CL will introduce treatment of those assignments as early errors.

Implementation of the harmony block scoped let bindings as proposed here: http://wiki.ecmascript.org/doku.php?id=harmony:block_scoped_bindings Changes to the syntax are explained there. They are active under the harmony_block_scoping_ flag in the parser.

When deoptimizing to after an expression of the form (expr0 || expr1) or (expr0 && expr1) in an effect context, the unoptimized code could incorrectly see the value of the expression. Handle the short-circuit binary operators specially in effect contexts. This fixes the issue and will generate better code when the left subexpression is boolean-valued.

If the instanceof stub was requested to deliver true/false objects as the result instead of 0/1 then 0/1 was actually returned if the builtin INSTANCE_OF ended up being called. This is now fixed.

In the shell sample don't print the result of executing a script, only evaluating expressions. Fixed issue when building samples on Windows using a shared V8 library. Added visibility option on Linux build which makes the generated library 18% smaller. Changed build system to accept multiple build modes in one build and generate seperate objects, libraries and executables for each mode. Removed deferred negation optimization (a * -b => -(a * b)) since this visibly changes operand conversion order. Improved parsing performance by introducing stack guard in preparsing. Without a stack guard preparsing always bails out with stack overflow. git-svn-id: http://v8.googlecode.com/svn/branches/bleeding_edge@16 ce2b1a6d-e550-0410-aec6-3dcde31c8c00
