[Headers][X86] Allow AVX2/AVX512 broadcast intrinsics to be used in Constexpr (#153363)
Fix [issue](#152499) This patch adds support for the following broadcast intrinsics by wrapping them around existing generic shuffle implementations: ``` _mm_broadcastb_epi8 _mm_broadcastw_epi16 _mm_broadcastd_epi32 _mm_broadcastq_epi64 _mm_broadcastss_ps _mm_broadcastsd_pd _mm256_broadcastb_epi8 _mm256_broadcastw_epi16 _mm256_broadcastd_epi32 _mm256_broadcastq_epi64 _mm256_broadcastss_ps _mm256_broadcastsd_pd _mm256_broadcastsi128_si256 _mm512_broadcastb_epi8 _mm512_broadcastw_epi16 _mm512_broadcastd_epi32 _mm512_broadcastq_epi64 _mm512_broadcastss_ps _mm512_broadcastsd_pd _mm512_broadcast_f32x2 _mm256_broadcast_f32x2 _mm512_broadcast_i32x2 _mm256_broadcast_i32x2 _mm_broadcast_i32x2 _mm512_broadcast_f32x4 _mm256_broadcast_f32x4 _mm512_broadcast_i32x4 _mm256_broadcast_i32x4 _mm512_broadcast_f32x8 _mm512_broadcast_i32x8 _mm512_broadcast_f64x2 _mm256_broadcast_f64x2 _mm512_broadcast_i64x2 _mm256_broadcast_i64x2 _mm512_broadcast_f64x4 _mm512_broadcast_i64x4 ``` Co-authored-by: Simon Pilgrim <[email protected]>
