    javascript.lang: Use binding for catch statement parameter
    
    According to the spec, destructuring binding is allowed for the catch
    statement parameter. (I don't believe this has been mentioned in any
    other JS documentation.)
    
    This also renames the catch-statement-exception context to
    catch-statement-parameter.
