Richard Henderson 22437b4de9 util/bufferiszero: Add simd acceleration for aarch64 
Because non-embedded aarch64 is expected to have AdvSIMD enabled, merely
double-check with the compiler flags for __ARM_NEON and don't bother with
a runtime check.  Otherwise, model the loop after the x86 SSE2 function.

Use UMAXV for the vector reduction.  This is 3 cycles on cortex-a76 and
2 cycles on neoverse-n1.
