Add simple implementations of performance.mark/performance.measure --
these aren't fully to spec, and in particular don't have the right base
class or prototype, but they're similar enough for simple use.
Additionally, log trace events for performance.measure, similar to
Chromium -- this allows us to annotate traces collected with d8's
--enable-tracing.
