I assume the 'i' here just stands for Intel. The 'mm' is just historic legacy due to the earlier file names. x86intrin.h was created by gcc to hold the intrinsics not specified by Intel.

Use that for SIMD intrinsics. You only need the even-larger (and slightly slower to compiler) x86intrin.h or intrin.h if you need stuff like integer rotate / bit-scan intrinsics (although Intel documents some of those as being available in immintrin.h in their intrinsics guide). –
