[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.
