b68fba4dc8 [test] Use glyph ids instead of forcing ft funcs 
We were using ft funcs because these are CFF fonts, but we can avoid
glyph names instead and keep testing both ot and ft.

the --verify in run-tests.sh checks what we are interested in.

0e63cbed9c [test] Fix difference between ft and ot font funcs 
See https://github.com/behdad/harfbuzz/pull/590#issuecomment-341194673.

I simply removed the composite glyph and use the referenced simple
glyph directly.

70137e2b4b [test] We don’t care about glyph positions here 
Freetype and OT font functions give different positions for some glyphs
in this font (OT seems to be correct), but that is not what we are
interested in in this test.

81e2b9b8a9 Never skip over CGJ 
We might want to tweak this some more.  For now, never skipping over
it is better behavior than always skipping.

5d98de1f38 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.

Before 71c0a1429d GURMUKHI used to be at 15,
because Uniscribe seems to allow this character standalone, but that looks
wrong.

8b2c94c43f 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.

Example Burmese senquence:

  U+1004,U+103A,U+1039,U+101B,U+103D,U+102D
