b6aa2d71f3 [gvar] Speed up calculate_scalar more 
Use a gvar-wide cache of the one active peak index for shared-tuples
that have only one active peak. This speeds up the scalar calculation.

This shows significant speedup for the CJK VarComposite font for
example since that has tens of axes with mostly only one active peak.

e428edc371 [unicode] Fix typo 
I believe the `hb-unicode.h` has a typo where `HB_UNICODE_COMBINING_CLASS_CCC133	= 132,` is supposed to be `HB_UNICODE_COMBINING_CLASS_CCC132`

63afb4f2e7 [syllabic] Better fix for previous issue 
With previous fix the GPOS application was still reading the syllable()
member, which was already freed.  This fix is more correct.

c5f3b3feb1 [syllabic] Actually clear syllables 
Such that they don't affect GPOS.

I broke this in 044d7a06db.

2175f5d050 [subset] Fix inefficient ItemVariationStore subsetting w/ retain_gids. 
ItemVariationStore is relying on the assumption that the inner_map is populated for all output glyphs, this is not true for subsetting operations with retain gids enabled. Fixes fuzzer timeout: https://oss-fuzz.com/testcase-detail/4575222591520768.

385e23762d [var] Optimize calculate_scalar more 
This change alone is showing me 14% scalar in a benchmark.
The reason being that the array::operator[] is not being invoked
a lot of time, which was, many times, hitting the unlikely() path.
Weird!
