Behdad Esfahbod e2b878055b Disable OTL processing for Hebrew if GPOS doesn't have Hebrew subtable
New approach to fix this:
69f9fbc420

Previous approach was reverted as it was too broad.  See context:
https://github.com/behdad/harfbuzz/issues/347#issuecomment-267838368

With U+05E9,U+05B8,U+05C1,U+05DC and Arial Unicode, we now (correctly) disable
GDEF and GPOS, so we get results very close to Uniscribe, but slightly different
since our fallback position logic is not exactly the same:

Before:		[gid1166=3+991|gid1142=0+737|gid5798=0+1434]
After:		[gid1166=3+991|gid1142=0@402,-26+0|gid5798=0+1434]
Uniscribe:	[gid1166=3+991|gid1142=0@348,0+0|gid5798=0+1434]

Behdad Esfahbod 9e834e29e0 [hebrew] Zero mark advance by GDEF late
Seems to be what Uniscribe does.

At this point I think it's work checking our default...

Fixes Bug 76767 - Zeroing of advance of 2nd component of multiple
substitution with SBL Hebrew
https://bugs.freedesktop.org/show_bug.cgi?id=76767

Micro-test added.

Behdad Esfahbod 7627100f42 Mark unsigned integer literals with the u suffix
Simplifies hb_in_range() calls as the type can be inferred.
The rest is obsessiveness, I admit.

Behdad Esfahbod a82165248c Only do fallback Hebrew composition if no GPOS 'mark' available
Apparently some modern fonts have proper GPOS mark positioning
tables, but undesirable precomposed forms!  See thread
"Hebrew composition to presentation forms" and:

  http://tex.stackexchange.com/questions/156775/having-trouble-with-vowel-positioning-in-ezra-sil-xelatex

Test case: U+fb1d,05d9,05b4
