[PATCH 2/2]AArch64: Use vectorizer initial unrolling as default

Hi All, The vectorizer now tries to maintain the target VF that a user wanted through uncreasing the unroll factor if the user used pragma GCC unroll and we've vectorized the loop. This change makes the AArch64 backend honor this initial value being set by the vectorizer. Consider the loop void
