Khaled Hosny da5118da77 [ot-shape] Enable abvm/blwm features by default
Core Text seems to apply them to Latin text, but Uniscribe doesn’t.

Current behavior unchanged if this flag is not set (and it isn't by default).

That function checks for buffer->successful already.  No need

Behdad Esfahbod 35d410f2ba Remove ASSERT_POD
Newer compilers / language allows structs with constructor in union.
So, this was not actually testing anything.  Indeed, the recent
change in DISALLOW_COPY *is* making some of our types non-POD.
That broke some bots.

Just remove this since it wasn't doing much, and I'd rather have
DISALLOW_COPY.

Show up with gcc -O0.

There's a few more but those are functions that need to be filled in.

Maybe this is a lost battle...

Behdad Esfahbod 5143654716 [khmer] Rewrite grammar completely
Based on experimenting with Uniscribe to extract grammar and categories.

Failures down from 44 to 35:

KHMER: 299089 out of 299124 tests passed. 35 failed (0.0117008%)

We still don't enforce the one-matra rule pre-decomposition, but enforce
an order and one-matra-per-position post-decomposition.

Behdad Esfahbod b1e07e1e6c [indic/khmer] Remove use of global constructors
Alternative woul have been to resurrect F_COMBINE that I removed in
70136a78cb

But this does it for now.  I'm not sure why check-static-inits.sh didn't
catch this before.  Clang -Weverything bot did:

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

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.
