[AArch64] Enable merging of adjacent zero stores for all subtargets. This optimization merges adjacent zero stores into a wider store. e.g., strh wzr, [x0] strh wzr, [x0, #2] ; becomes str wzr, [x0] e.g., str wzr, [x0] str wzr, [x0, #4] ; becomes str xzr, [x0] Previously, this was only enabled for Kryo and Cortex-A57.
