[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.
