GPU part of calculation of squared exponential kernel.

Parameters

[in]	x	input vector or matrix
[out]	res	squared distances between elements of x
	sigma_sq	squared standard deviation
	neg_half_inv_l_sq	-0.5 / square(length scale)
	size	number of elements in x
	element_size	the number of doubles that make one element of x
