Extend sunspider driver to be able to run kraken

https://bugs.webkit.org/show_bug.cgi?id=71799

Patch by Andy Wingo <wingo@igalia.com> on 2011-11-15
Reviewed by Filip Pizlo.

* resources/sunspider-standalone-driver.js: Try to load a -data
file.  If that succeeds, we have a kraken-like test, so we time
the test using `load'.  Otherwise fall back to using `run'.
