Behdad Esfahbod 91c60802e6 [open-type] Fix overflow check
Without the cast, the compiler is within its rights to reason that
overflow didn't happen and optimize away the check, as clang was.

Behdad Esfahbod f3151b6582 [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.

Behdad Esfahbod 9843f07658 [OffsetTo] Try catching nullable offsets to unbounded types
Doesn't catch all cases; if type is not fully defined at
OffsetTo time, we can't know.

Fixes https://github.com/harfbuzz/harfbuzz/issues/1300
to the best we can do.

Behdad Esfahbod 7c4e9080c0 [sanitize] Minor trace format fixup
This likely() is unlikely to make a difference, and obscures
the return_trace() message by writing out "something" instead
of the true/false value.

Garret Rieger 0da9158f62 [subset] Remove OffsetTo::serialize().
Convert remaining uses of it to serialize_serialize() which correctly uses the object packer.

Garret Rieger 35458b6b66 [subset] Add serialize_serialize to OffsetTo.
Similar to serialize_subset() this will serialize the new object and then link it to the offset.

Behdad Esfahbod 70110f6aaa Modify OffsetTo<>::sanitize() overflow check
The code in question was introduced in 70eb2ff682.
Rewrite it to not call sanitizer check_range() as we want to use
check_range() for byte accounting.
