[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.
