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.

9c2518988d [repack] Don't count space isolation against round limit. 
Restore max rounds to 20 but don't count space isolation against the limit. The number of iterations space isolation can make changes for is already bounded to a reasonable max (the number of lookups in the font) so no need to cap the number of iterations.
