x64 always has MMX, MMXEXT, SSE and SSE2 and this means
that some functions for MMX, MMXEXT and 3dnow are always
overridden by other functions (unless one e.g. explicitly
disables SSE2) for x64. So given that the only systems that
benefit from ff_scalarproduct_and_madd_int16_mmxext are truely
ancient 32bit x86s it is removed.

None of them are specific to the YASM assembler.

The unique user so far is wmalossless 24bits. The few samples tested show an
order of 8, so more unrolling or an avx2 version do not make sense.
Timings: 68 -> 49 cycles

Their intent was to make the DSP work with wmalossless pro.
The later was fixed to work with the DSP.
