/**
* Returns the index of the first element in a strided array which is not equal to a corresponding element in another strided array using alternative indexing semantics.
*
* ## Notes
*
* - If the function is unable to find an element in `x` which is not equal to a corresponding element in `y`, the function returns `-1`.
*
* @param {PositiveInteger} N - number of indexed elements
* @param {Collection} x - first input array
* @param {integer} strideX - stride length for `x`
* @param {NonNegativeInteger} offsetX - starting index for `x`
* @param {Collection} y - second input array
* @param {integer} strideY - stride length for `y`
* @param {NonNegativeInteger} offsetY - starting index for `y`
* @returns {integer} index
*
* @example
* var x = [ 0, 0, 1, 0 ];
* var y = [ 0, 0, 0, 0 ];
*
* var idx = gfirstIndexNotEqual( x.length, x, 1, 0, y, 1, 0 );
* // returns 2
