Adjust normalizer for out-of-order marks
...
We are going to implement Unicode Arabic Mark Ordering Algorithm:
http://www.unicode.org/reports/tr53/tr53-1.pdf
which will reorder marks out of their sorted ccc order. Adjust
normalizer to stop combining as soon as dangerous ordering is
detected.

Tweak mark-base attachment
...
Apparently a base glyph can also become an attached component of a
ligature if the ligature-forming lookup used IgnoreBase. This was
being confused with a non-first component of a MultipleSubst and
hence not matched for mark-attachment. Tweak test to fix.

Tweak ligature component matching for ligature formation

If two marks want to ligate and they belong to different components of the
same ligature glyph, and said ligature glyph is to be ignored according to
mark-filtering rules, then allow.
