Chris Tate 4004d4c9d0 Answer 511 for an empty event-loop-delay histogram's percentiles ...

Node creates monitorEventLoopDelay's histogram with a lowest discernible
value of 1000 ns, so an empty histogram's percentile() returns 511, the
highest value its first bucket holds. The runtime returned 0.

6397-event-loop-metrics.ts now skips a sampling window that has no
recorded delta. A delta needs two samples after reset(), and a loop that
wakes late runs only one sample in a window, so on a loaded machine the
program printed an empty window under Node and compiled alike. The
program also prints percentile(50) after each reset.
