Now that ES2015 const has shipped, in Chrome 49, legacy const declarations are no more. This lets us remove a bunch of code from many parts of the codebase. In this patch, I remove parser support for generating legacy const variables from const declarations. This also removes the special "illegal declaration" bit from Scope, which has ripples into all compiler backends. Also gone are any tests which relied on legacy const declarations. Note that we do still generate a Variable in mode CONST_LEGACY in one case: function name bindings in sloppy mode. The likely fix there is to add a new Variable::Kind for this case and handle it appropriately for stores in each backend, but I leave that for a later patch to make this one completely subtractive.

This patch moves the semantics of 'const' in sloppy mode to match those in strict mode, that is, const makes lexical (let-like) bindings, must have an initializer, and does not create properties of the global object.

Removes 6 out of 8 of our remaining unintentional failures on test262. Also fixes treatment of inherited setters added after the fact. Specifically: - In the runtime, when looking for setter callbacks in the prototype chain, also look for read-only properties. If one is found, reject (exception in strict mode). If a proxy is found, invoke proper trap. Note: this folds in the CanPut function from the spec and avoids an extra lookup over the prototype chain. - In generated code for stores, insert a test for the maps from the prototype chain, but only up to the object where the property already exists (which may be the object itself). In Hydrogen, if the found property is read-only or not cacheable (e.g. a proxy), bail out; in a stub, generate an unconditional miss (to get an exception in strict mode). - Add test cases and adapt existing test expectations.

Encapsulate the helper functions in mjsunit.js. Now only exposes the exception class and the assertXXX functions. Make assertEquals use === instead of ==. This prevents a lot of possiblefalse positives in tests, and avoids having to do assertTrue(expected === actual) when you need it. Fixed some tests that were either buggy or assuming == test.

All uses of %AddProperty are replaced by %SetProperty. A few uses of IgnoreAttributesAndSetLocalProperty are added, and the runtime version of it adds a PropertyAttributes argument. Only the JSObject class in objects.cc now uses AddProperty, and it can become private.

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
