4c853be6 - [AArch64] Replace uaddlv with addv for popcount operation (#121934)

[AArch64] Replace uaddlv with addv for popcount operation (#121934) Replace `uaddlv` with `addv` for popcount operation as it is simpler operation. On certain platforms like Cortex-A510, `addv` has a latency of 3 cycles whereas `uaddlv` has a latency of 4 cycles GCC generates `addv` as well: https://godbolt.org/z/MnYG9jcEo
