Behdad Esfahbod c88a6a9ec3 [face] Remove const from get_user_data prototype 
This was done by mistake.

Since the returned user_data can be changed, face should not be marked
const. Other object types follow this parttern.

Behdad Esfahbod 5a058ba158 [shape-fuzzer] Add commented out more buffer-verify option 
Those currently fail and I've been unable to debug them.

I tried two, passing them to hb-shape doesn't reproduce the failure. :(

Behdad Esfahbod 9a2a857043 [ot-shape] Don't verify buffer if shaping failed 
Fixes all of fuzzing verify failures, which were result of buffer failure
on super-long results, which fails unsafe-to-break because shorter strings
don't fail shaping.

Behdad Esfahbod ea2dd54b68 [map] Place item hash between key and value, not after them 
This way if only one of key and value is 64bit (eg. pointer), and other is 32bit,
the whole item will fit in 128bit, whereas before it would have been bumped up to
196 if only value was 64bit (a common use-case for us.)
