[ArrayOf family] Use memory barrier before accessing array
...
Without it, the compiler was reordering and batching the read
of array length and array[0] if the 0'th member was accessed
constantly and function was inlined. This felt safe to the
compiler because HB_VAR_ARRAY is 1, but could be unsafe actually.
The memory barrier disallows that.
This was found by afl/honggfuzz address sanitizers.

hb_graphite2_cluster_t::advance can apparently be negative
...
...as seen with HarfBuzz used by LibreOffice, with `instdir/program/soffice
--headless --convert-to pdf` of doc/abi6073-2.doc from the LibreOffice crash-
testing corpus when run under UBSan,

(where in frame #4 GenericSalLayout::LayoutText, pHbBuffer->props.direction is
HB_DIRECTION_RTL, in case that is relevant).
It is unclear to me whether it is sufficient to only change
hb_graphite2_cluster_t::advance from signed to unsigned int, as there are other
unsigned int variables (like curradv in _hb_graphite2_shape) whose value depend
on hb_graphite2_cluster_t::advance, and which thus might also become negative.
But unlike the float -> unsigned int conversion that UBSan warned about here
(where gr_slot_origin_X() and xscale are float), those are signed int ->
unsigned int conversions that do not cause undefined behavior. At least, with
this change, the above --convert-to pdf and a full `make check screenshot`
succeeded for me under without further UBSan warnings.
(For the version of HarfBuzz optionally built as part of the LibreOffice build,
this has been addressed with
<https://git.libreoffice.org/core/+/6e53e03f752c2f85283c4d47efaaf0683299783c%5E!/ >

These three characters have Indic_Syllabic_Category=Consonant_Placeholder. The
original evidence that prompted these overrides says they can take tone marks.
They are not subjoined: Khamti Shan apparently does not use subjoined
characters at all. Therefore, PLACEHOLDER is good enough and these need not be
overridden to C.

[layout-cache] Cache lookahead, not input, classdef in ChainContextFormat2
...
From the commit:
+ /* For ChainContextFormat2 we cache the LookaheadClassDef instead of InputClassDef.
+ * The reason is that most heavy fonts want to identify a glyph in context and apply
+ * a lookup to it. In this scenario, the length of the input sequence is one, whereas
+ * the lookahead / backtrack are typically longer. The one glyph in input sequence is
+ * looked-up below and no input glyph is looked up in individual rules, whereas the
+ * lookahead and backtrack glyphs are tried. Since we match lookahead before backtrack,
+ * we should cache lookahead. This decisions showed a 20% improvement in shaping of
+ * the Gulzar font.

[layout] Use a cache for main input ClassDef of (Chain)ContextLookupFormat2
...
This commit adds a per-lookup caching infrastructure to GSUB/GPOS, and
uses it to cache input ClassDef.get_class value for (Chain)ContextLookupFormat2.
For fonts heavy on use of heave class-based2 context matching, this shows
a good speedup. For NotoNastaliqUrdu for example, I observe 17% speedup.
Unfortunately not many other lookups can use a cache like this :(.

Fix check-* scripts when harfbuzz is a subproject

the absolute path and make it relative to current source dir.

[cff-common] No need to check max-offset in INDEX
...
The length_at() function makes sure out-of-range offsets
are discarded. We just need to check the last offset.

[subset] Fix cpal subsetting when there are partial palette overlaps.
...
The existing code doesn't correctly handle the case where palettes partially overlap in the color record array. This changes the subsetting to only share entries in the color record array when palettes have the same first color index. Partially overlapping palettes will be converted to disjoint segments in the color record array.
Updates one of the color tests to use multiple palettes.
Also fixes fuzzer: https://oss-fuzz.com/testcase-detail/5568200165687296 .

[subset] bug fix in prune_langsys
...
we should not cache visited langsys cause 2 different Record<Langsys>
could have different Tag while pointing to the same Langsys, a langsys
is redundant in Record<Langsys> A does not mean it's redundant in Record
B. Same thing for visited_script.
Also adding the number of features in the LangSys's feature list to the
visited langsys count so it's more accurate.
Plus some improvement in langsys compare()

[layout] Fix handling of baseline variations
...
For BASE table format 1.1, the handling of design
space vs user space coordinates was inconsistent.
We were applying design -> user transformation
twice for the deltas, leading to wrong baseline
values.
