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.

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.
