revsetlang: match tree by helper function on optimize

This should make optimize() more readable and less error-prone, but it doubles
the parsing cost.

  (original)
  $ python -m timeit -n10000 -s 'from mercurial import revsetlang as L' \
  'L.optimize(L.analyze(L.parse("ancestors(x) and not ancestors(y)")))'
  10000 loops, best of 3: 79.3 usec per loop

  (this patch)
  $ python -m timeit -n10000 -s 'from mercurial import revsetlang as L' \
  'L._treecache.clear(); \
   L.optimize(L.analyze(L.parse("ancestors(x) and not ancestors(y)")))'
  10000 loops, best of 3: 201 usec per loop
