/**
* Simultaneously computes the sine and cosine of an angle measured in radians on the interval \\( \approx \[-\pi/4, \pi/4\] \\) (except for \\(-0\\)), where \\( \pi/4 \approx 0.7854 \\).
*
* @private
* @param {number} x - input value (in radians, assumed to be bounded by `~π/4` in magnitude)
* @param {number} y - tail of `x`
* @returns {Array<number>} sine and cosine
*
* @example
* var v = kernelSincos( 0.0, 0.0 );
* // returns <Float64Array>[ ~0.0, ~1.0 ]
*
* @example
* var v = kernelSincos( 3.141592653589793/2.0, 0.0 );
* // returns <Float64Array>[ ~1.0, ~0.0 ]
*
* @example
* var v = kernelSincos( -3.141592653589793/6.0, 0.0 );
* // returns <Float64Array>[ ~-0.5, ~0.866 ]
*
* @example
