specialize Js.Dict.fromArray

[bobzhang]

part of #734
Currently there is no way to generate JSON object below:

{ "key1" : value1,
  "key2" : value2}

the closest one is Js.Dict.fromArray : (string * Js.Json.t) array -> Js.Json.t Js.Dict.t) but it results in a runtime call.

Js.Dict.fromArray [ "x", x ; "z", z]

Generated JS should be

{ "x" :  x ,
   "z" : z}
