This change adds proper support for loongarch64 using LASX SIMD instructions. The SIMD support is gated behind a new `nightly` feature since it requires the unstable `stdarch_loongarch` feature. Fixes compilation errors on `u8x16` by: 1. Using `v32i8` (256-bit) instead of `v16i8` (128-bit) for the vector type 2. Fixing incorrect function names (lasx_xvand → lasx_xvand_v, lasx_xvadds_bu → lasx_xvadd_b) 3. Fixing argument types (cast u8 to i32 for lasx_xvreplgr2vr_b) 4. Fixed shift constant type (N: u32 instead of i32) 5. Added scalar fallback for missing lasx_xvpermi_b Assisted-by: Claude:ark-code-latest
