50bcf681 - [X86][bytecode] Allow SSE/AVX BLEND imm intrinsics to be used in constexpr (#157776)

[X86][bytecode] Allow SSE/AVX BLEND imm intrinsics to be used in constexpr (#157776) This marks the following builtins as constexpr, which allows their corresponding intrinsics to be used in constexprs. | Intrinsics | X86 Builtins | CPUID Flags | Header | | -------------------- | --------------------------- | ----------- | ----------- | | `_mm_blend_pd` | `__builtin_ia32_blendpd` | SSE4.1 | smmintrin.h | | `_mm256_blend_pd` | `__builtin_ia32_blendpd256` | AVX | immintrin.h | | `_mm_blend_ps` | `__builtin_ia32_blendps` | SSE4.1 | smmintrin.h | | `_mm256_blend_ps` | `__builtin_ia32_blendps256` | AVX | immintrin.h | | `_mm_blend_epi16` | `__builtin_ia32_pblendw128` | SSE4.1 | smmintrin.h | | `_mm256_blend_epi16` | `__builtin_ia32_pblendw256` | AVX2 | immintrin.h | | `_mm_blend_epi32` | `__builtin_ia32_pblendd128` | AVX2 | immintrin.h | | `_mm256_blend_epi32` | `__builtin_ia32_pblendd256` | AVX2 | immintrin.h | Fixes #157065 --------- Co-authored-by: Timm Baeder <tbaeder@redhat.com> Co-authored-by: Simon Pilgrim <llvm-dev@redking.me.uk>
