   Use this to work around those restrictions (which should hopefully all get
    optimized to a single MOVD instruction).

+  LLVM implemented _mm_loadu_si32() since Clang 8.0, however the
+   __clang_major__ version number macro is unreliable, as vendors
+   (specifically, Apple) will use different numbering schemes than upstream.
+  Clang's advice is "use feature detection", but they do not provide feature
+   detection support for specific SIMD functions.
+  We follow the approach from the SIMDe project and instead detect unrelated
+   features that should be available in the version we want (see
+   <https://github.com/simd-everywhere/simde/blob/master/simde/simde-detect-clang.h>).*/
