[PATCH] clang-format: [JS] Fix function formatting

[Daniel Jasper]

Based on the tests, I think this is (or at least might be) the wrong fix. For example, there can be function literals with names in other expression contexts, not just in braced lists, e.g.:

  var variablename = function FunctionName(Argument List) { 
    // Function Body 
  };

I'll ponder this some more and get back to you.
