aarch64 SIMD instructions not working on aarch64-apple-darwin but work on aarch64-unknown-linux-gnu #143201

Description

@zzau13

The same SIMD code using AArch64 intrinsics compiles and runs successfully for the aarch64-unknown-linux-gnu target, but fails on aarch64-apple-darwin. The endianess is the same (little-endian) on both platforms.

❌ macOS (fails):
