[X86] Remove unnecessary MMX declarations from Intrin.h

As discussed in PR23648 - the intrinsics _m_from_int, _m_to_int and _m_prefetch are defined in mmintrin.h and prfchwintrin.h so we don't need to in Intrin.h

Added tests for _m_from_int and _m_to_int

D11338 already added a test for _m_prefetch
