It adds support for the following X86 builtins: - __builtin_ia32_shuf_f32x4 - __builtin_ia32_shuf_f64x2 - __builtin_ia32_shuf_i32x4 - __builtin_ia32_shuf_i64x2 - __builtin_ia32_shuf_f32x4_256 - __builtin_ia32_shuf_f64x2_256 - __builtin_ia32_shuf_i32x4_256 - __builtin_ia32_shuf_i64x2_256 Part of https://github.com/llvm/llvm-project/issues/167765
