Currently the SunSpider test driver lacks an option to run a test suite that
will test JavaScriptCore parsing performance only. This patch adds just such
a test suite and option to SunSpider as well as the jsc test shell. I've included
three large javascript source files found in the wild: jquery, mootools and prototype.
Combined with the concatenation of all three, these form a new testsuite to measure
and test pure JavaScriptCore parsing performance.
