This patch cleans up those references to be consistent with current practice and thus less confusing.

Added trace event to V8WindowShell::initializeIfNeeded. This is part of an effort to identify what contributes to the ~12.6% "uncategorized" time from the android top 25k experiment. For sites high in uncategorized time, this accounts for about 3.8% of the trace.
