      Remove support for legacy const, part 1 · ed18aa65
      adamk authored
      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.

      Ship ES2015 sloppy-mode const semantics · 95145fa8
      littledan authored
      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.
