            Bug ID: 141257
           Summary: Web Inspector: ES6: Better support for Symbol types in
                    Type Profiler

* SUMMARY
We should better support for Symbol types in Type Profiler. Symbols are pseudo-primitives, like unique strings. I would expect them to be handled similar to Strings in the Type profiling.

* TEST
<script>
function foo(a) {
  console.log(a);
}
</script>

js> foo(Symbol()); // I expect "Symbol" to show up next to foo's `a` param.
js> foo(1); // I expect "(many)" to show up next to foo's `a` param. Popover should have "Integer" and "Symbol".

* NOTES
- Symbol has some special properties. But it is more like a primitive than an object.
