    ICU-20250 make UnicodeSet(intprop=value) faster
    - fastpath for UnicodeSet.add(new last range)
    - fewer UnicodeSet memory allocations:
      initial internal list array, exponential array growth,
      allocate strings list/set only when first one is added
    - faster CodePointTrie.getRange(): fewer calls to filter function
    - revert UnicodeSet(intprop=value) from trie ranges to range starts + lookup
    - cache per-int-prop range starts: fewer lookups
    (cherry picked from commit 98f9170004c29388d756a8a283573164a7a26bef)
