Once #154113 / #131995 has landed the AVX512CD lzcnt intrinsics should be updated to use the generic elementwise builtin and test added for constexpr coverage
- [ ] Convert _mm_lzcnt_epi32 etc. (inc mask/maskz variants) to use __builtin_elementwise_ctlz
- [ ] Remove builtin_ia32_vplzcnt builtins
- [ ] Add constexpr test coverage
