The includes should make more sense now and not just happen to compile due to headers included from other headers. Used a modified version of IWYU. Modifications were to attribute int8_t and so on to stdint.h instead of sys/types.h and immintrin.h instead of more specific headers. include-what-you-use 0.7 (git:b70df35) based on clang version 3.9.0 (trunk 264728)
