Behdad Esfahbod 0291a65286 Further adjust mark advance zeroing 
This is a followup to 568000274c.
Looks like in the Latin shaper, Uniscribe zeroes all Unicode NSM
advances *after* GPOS, not before.  Match that.

Can be tested using DejaVu Sans Mono, since that font has GPOS
rules to zero the mark advances on its own.

Behdad Esfahbod 568000274c Adjust mark advance-width zeroing logic for Myanmar 
Before, we were zeroing advance width of attached marks for
non-Indic scripts, and not doing it for Indic.

We have now three different behaviors, which seem to better
reflect what Uniscribe is doing:

  - For Indic, no explicit zeroing happens whatsoever, which
    is the same as before,

  - For Myanmar, zero advance width of glyphs marked as marks
    *in GDEF*, and do that *before* applying GPOS.  This seems
    to be what the new Win8 Myanmar shaper does,

  - For everything else, zero advance width of glyphs that are
    from General_Category=Mn Unicode characters, and do so
    before applying GPOS.  This seems to be what Uniscribe does
    for Latin at least.

With these changes, positioning of all tests matches for Myanmar,
except for the glitch in Uniscribe not applying 'mark'.  See preivous
commit.

Behdad Esfahbod 1c8654ead4 [Myanmar] Prevent reordering between Asat and Dot below 
Implemented as a hack for now.  Myanmar failures down from 23 to 15.

MYANMAR: 1123868 out of 1123883 tests passed. 15 failed (0.00133466%)

The remaining 15 cases are all where the syllable is wrong according to
the OpenType spec.  We insert dottedcircle.  Uniscribe fails to do that,
but it also fails to reorder the prebase-reordering medial-Ra.  So it
gets it wrong.

Behdad Esfahbod 54f7b4d9ec [OTLayout] Respect lookup-flags skipping over non-mark glyphs 
Before, when matching ligatures, we never skipping over base / liga
glyphs even if that was what the LookupFlags asked for.

Fixed now.  We carefully reviewed all instances of this, and tested with
Amiri as well as some Indic scripts, and are confident that this should
NOT break anyone's fonts.  It's also how Uniscribe does it, from what
we can tell.

Behdad Esfahbod 6e74c64211 Improve normalization heuristic 
Before, for most scripts, we were not trying to recompose two characters
if the second one had ccc=0.  That fails for Myanmar where U+1026
decomposes to U+1025,U+102E, both of which have ccc=0.  However, we do
want to try to recompose those.  We now check whether the second is a
mark, using general category instead.

At the same time, remove optimization that was conflicting with this.

[Let the Ngapi hackfest begin!]

This reverts commit fab7a71f11.

Conflicts:
	src/hb-ot-shape-complex-indic-machine.hh

Keeping that generated file in-tree causes problems with processes like
tinderbox  that automatically fetch and build harfbuzz.  It's harder to
bootstrap harfbuzz now (as was previously), but I'm willing to give this
another chance and see how it goes.
