LibJS: Forward a string aproximation of the CallExpression to Call Ops

Browse source 
This gives us better debug output when analysing calls to `undefined`
and also fixes multiple test-js cases expecting an
`(evaluated from $Expression)` in the error message.

This also refactors out the generation of that string, to avoid code
duplication with the AST interpreter.
