Behdad Esfahbod 099472e08b hb_buffer_diff() tweak 
I like to have a mode where CONTAINS_NOTDEF and CONTAINS_DOTTEDCIRCLE are not
returned.  Abused a value of -1 for that.  hb-shape now uses it.  Fixes two
of the six tests failing with --verify in test/shaping/run-tests.sh.

Behdad Esfahbod 05fabbd03e [unsafe-to-break] Towards verifying unsafe-to-break in --verify 
We break and shape fragments and reconstruct shape result from them.
Remains to compare to original buffer.  Going to add some buffer
comparison API and use here, instead of open-coding.

Behdad Esfahbod ec104e5912 [unsafe-to-break] Mark unsafe is cluster merging is disabled 
We were relying on cluster merges not requiring unsafe flagging because
they get merged.  If cluster level requests no merging, then we flag
unsafe when merge would have happened.
