  Disable OTL processing for Hebrew if GPOS doesn't have Hebrew subtable
  
  New approach to fix this:
  https://github.com/behdad/harfbuzz/commit/69f9fbc4200442a35484d3c790ae8f4979be5d60
  
  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]
