ARM64: Tune SIMD loop unrolling factor heuristic.
Improve SIMD loop unrolling factor heuristic for ARM64 by
accounting for max desired loop size, trip_count, etc. The
following example shows 21% perf increase:
for (int i = 0; i < LENGTH; i++) {
bc[i] = ba[i]; // Byte arrays
}
Test: test-art-host, test-art-target.
