Revert "[VarData] Don't clear memory we are going to fill in completely"
This reverts commit e28e2dad03a453c5e5c4c5a9d6fd276182c5f80b.
This made fuzzer unhappy. I'm not sure how.

[subset] Always output Lookup's even if they are empty.
The rest of layout subsetting depends on lookup indices being consistent with those computed during planning. So if an empty lookup is discarded during the subset phase it will invalidate all subsequent lookup indices. Generally we shouldn't end up with an empty lookup as we pre-prune them during the planning phase, but it can happen in rare cases such as when a subtable is considered degenerate (eg. #3853)

[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.

[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 :(.
