 """Removes ViewHostMsg_Close and alike from testcases. These messages are an
 annoyance for corpus distillation. They cause the browser to exit, so no
 further messages are processed. On the other hand, ViewHostMsg_Close is useful
 for fuzzing - many found bugs are related to a renderer disappearing. So the
 fuzzer should be crafting random ViewHostMsg_Close messages.
