GPU part of calculation of Matern exponential kernel.

Parameters

[in]	x	input vector or matrix
[out]	res	squared distances between elements of x
	sigma_sq	squared standard deviation
	neg_inv_l	-1.0 / length_scale
	size	number of elements in x
	element_size	the number of doubles that make one element of x
