8c7721e709 mxfdec: Fix Avid AirSpeed files being misinterpreted as OP1a 
The "ECs != 1 -> OP1a" assumption was wrong. Luckily, the file that triggered
that behavior had two ECs, not zero. Hence distinguishing between them is
simple in this case.

6eda85e15b sbrdsp.asm: convert all instructions to float/SSE ones. 
Since the values are floats, using the float operations
makes sense, improves performance on some CPUs and
makes the code SSE compatible instead of needing SSE2.

Based on suggestion by Jason.

7e1ce6a6ac dsputil: remove shift parameter from scalarproduct_int16 
There is only one caller, which does not need the shifting. Other use cases
are situations where different roundings would be needed.
