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.
