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.

These are only relevant to Sinhala, because they decompose in other
cases. The USE spec categorizes them all as VPst. No idea why we
weren't following that before.
clang warning:
../../util/options.hh:72:13: warning: destination for this 'memset' call is a pointer to dynamic class
'option_parser_t'; vtable pointer will be overwritten [-Wdynamic-class-memaccess]

Sure, gcc knows to warn about this as well:
../../util/options.cc:175:17: warning: this statement may fall through [-Wimplicit-fallthrough=]
case 1: m.r = m.t;
~~~~^~~~~
../../util/options.cc:176:5: note: here
case 2: m.b = m.t;
^~~~
But HOLY SMOKES, look at clang -Weverything bot message:
options.cc:176:5: warning: unannotated fall-through between switch labels [-Wimplicit-fallthrough]
case 2: m.b = m.t;
^
options.cc:176:5: note: insert 'HB_FALLTHROUGH;' to silence this warning
case 2: m.b = m.t;
^
HB_FALLTHROUGH;
Right, it's telling me to insert "HB_FALLTHROUGH;" there!!!!!!!!!
From clang -Weverything bot:
options.cc:39:3: warning: no previous extern declaration for non-static variable 'supported_font_funcs' [-Wmissing-variable-declarations]
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:
