Fixes for bug #1436:

- Replaced the dependency analysis in CevalFunction with a new that uses the
  Graph package, to fix bug 1436 (and probably more too).
- Added traversal function Expression.traverseExpBidir.
- Added function ComponentReference.crefEqualWithoutSubs, which compares two
  crefs but disregards their subscripts.
- Extended Expression.subscriptExp to handle more cases, and added
  subscriptIndexExp that has the old behaviour of only handling DAE.INDEX.
- Added test case mofiles/FunctionEval11 to test fix for bug 1436.
