      [es6] Implement spec compliant ToPrimitive in the runtime. · f6c6d713
      bmeurer authored
      This is the first step towards a spec compliant ToPrimitive
      implementation (and therefore spec compliant ToNumber, ToString,
      ToName, and friends).  It adds support for the @@toPrimitive
      symbol that was introduced with ES2015, and also adds the new
      Symbol.prototype[@@toPrimitive] and Date.prototype[@@toPrimitive]
      initial properties.
      
      There are now runtime functions for %ToPrimitive, %ToNumber and
      %ToString, which do the right thing and should be used as fallbacks
      instead of the hairy runtime.js implementations.  I will do the
      same for the other conversion operations mentioned by the spec in
      follow up CLs.  Once everything is in place we can look into
      optimizing things further, so that we don't always call into the
      runtime.
      
      Also fixed Date.prototype.toJSON to be spec compliant.
