* SUMMARY: Testing script with at least 64K of different string literals
* See http://bugzilla.mozilla.org/show_bug.cgi?id=159334
*
* Testing that script engine can handle scripts with at least 64K of different
* string literals. The following will evaluate, via eval(), a script like this:
*
* f('0')
* f('1')
* ...
* f('N - 1')
*
* where N is 0xFFFE
