  // In general, this should match the logic in com.sun.tools.javac.tree.Pretty.
  //
  // TODO(mdempsky): There are probably cases where we could omit parentheses
  // by tweaking the returned precedence, but they need careful review.
  // For example, consider a template to replace "add(a, b)" with "a + b",
  // which applied to "x + add(y, z)" would result in "x + (y + z)".
  // In most cases, we'd likely prefer "x + y + z" instead, but those aren't
  // always equivalent: "0L + (Integer.MIN_VALUE + Integer.MIN_VALUE)" yields
  // a different value than "0L + Integer.MIN_VALUE + Integer.MIN_VALUE" due
  // to integer promotion rules.
