[AArch64] Merge two adjacent str WZR into str XZR
Summary:
This change merges adjacent 32 bit zero stores into a 64 bit zero store.
e.g.,
str wzr, [x0]
str wzr, [x0, #4]
becomes
str xzr, [x0]
Therefore, four adjacent 32 bit zero stores will be a single stp.
e.g.,
str wzr, [x0]
str wzr, [x0, #4]
str wzr, [x0, #8]
str wzr, [x0, #12]
becomes
stp xzr, xzr, [x0]
