Behdad Esfahbod 6ddd669e20 [khmer] Clear syllables before presentation features 
Probably not what Uniscribe does, but good idea?

Behdad Esfahbod 8eef1964a7 [khmer] Revert previous change, and remove pauses 
This makes test suite happy again (at 44) while fixing the sequences
we were fixing, which were the following with KhmerUI.ttf:

  U+1789,U+17BC
  U+1789,U+17D2,U+1789
  U+1789,U+17D2,U+1789,U+17BC

Fixes rest of https://github.com/harfbuzz/harfbuzz/issues/974

Behdad Esfahbod 7c658ea2f2 [khmer] Apply ccmp after basic features

Behdad Esfahbod 1a96cc825d [khmer] Rewrite most of shaper to better follow spec 
Khmer spec has only one reordering phase, and only simple prebase
matra and Coeng-Ro reordering.  Implement that.  Specifically,
this was done to address recognizing different orders of the matra
and Coeng-Ro sequence.  That said, some combinations are now
reordered differently from Uniscribe.  Not clear if that's intended
or a bug in Uniscribe.  The following two sequences render the same
in Uniscribe whereas we reorder them differently:

  U+17A0,U+17D2,U+179A,U+17C2
  U+17A0,U+17C2,U+17D2,U+179A

For that reason, our test suite numbers regressed slightly.  Used
to be at 34 for fails, now at:

KHMER: 299080 out of 299124 tests passed. 44 failed (0.0147096%)

But generally a good change, and removed lots of code.

Behdad Esfahbod b1e5650c67 [atomic] Make pointer get op relaxed instead of acquire 
We only use it before cmpexch, so relaxed is fine and faster for
common case.

Behdad Esfahbod 66ccd8ac40 [serialize] Increase stage count from 8 to 32 
Indic shaper uses many stages.  Now we are provably not limiting
functionality whereas the previous limit of 8 was assuming real-world
practices.

Behdad Esfahbod e7737b41d7 Add sanitizer reference_table, also fix clang build 
Clang is being really peculiar.  Fix with:

-  inline hb_blob_t *sanitize (hb_blob_t *blob) { return c->sanitize<Type> (blob); }
+  inline hb_blob_t *sanitize (hb_blob_t *blob) { return c[0].template/*clang idiosyncrasy*/sanitize_blob<Type> (blob); }

Ebrahim Byagowi 0c1b287b72
Add a new API, hb_ot_layout_get_feature_name_ids (#976) 
This new API returns cvXX and ssXX related NameId, things like
featUiLabelNameId, featUiTooltipTextNameId, sampleTextNameId, ... of cvXX
and UINameId of ssXX, in a unified way.

However HarfBuzz currently doesn't expose an API for retrieving the actual
information associated with NameId from the `name` table and that should be
done separately.

Remove dump-fon (#1100) 
It had interesting stuffs like EXE parsing and
big-endian parsers but added in an attempt to find
a solution for #681 which later found not related.

Behdad Esfahbod a8cc0b5907 Remove TODO that is not gonna be done 
Previously the idea was to cache sanitize results externally (think,
in Fontconfig) and avoid resanitizing every time.  That's, not a good
idea.
