Message:

PerformanceTests/CSS/StyleSheetInsert.html has a time-dependent non-Gaussian distribution
​https://bugs.webkit.org/show_bug.cgi?id=97741

Reviewed by Antti Koivisto.

Reset the content in the iframe in each run so that the runtime from each run follows a normal distribution.
We can cleanup this code once my patch to replace the argument list of run by an object is landed.
