      (This is a breakout from JDK-8261238, which seems to be stuck in review limbo (https://github.com/openjdk/jdk/pull/2428). In order to make that one more concise, I factor out the display changes, which hopefully are non-controversial enough to get upstream easily.)

      NMT silently omits call sites in its report whose allocation rate is too small to get over a certain, hidden, threshold:
      - there is a hard wired threshold of 1K in the baseline collector
      - then, we skip all sites whose size is less than what the unit is (eg scale=G, we skip all allocations < 1G

      NMT should state how many call sites had been omitted.
