If sk_Caps.rewriteMatrixVectorMultiply is false, we generate the same code as before. If sk_Caps.rewriteMatrixVectorMultiply is true, and optimization is enabled, medium-precision multiplication of `matrix * vector` is rewritten in BinaryExpression as the sum of (m[0]*v[0] + m[1]*v[1] + ... + m[N]*v[N]).
