* SUMMARY: Testing functions having duplicate formal parameter names
*
* SpiderMonkey was crashing on each case below if the parameters had
* the same name. But duplicate parameter names are permitted by ECMA;
* see ECMA-262 3rd Edition Final Section 10.1.3
*
* NOTE: Rhino does not have toSource() and uneval(); they are non-ECMA
* extensions to the language. So we include a test for them at the beginning -
