This PR will adds two mixed precision versions of ILU0 on GPU.
Both store compute the ILDU factorization as double, but casts it to floats afterwards, with the thinking that the apply will be faster if the matrix requires less memory movement. The two mixed precision variants differ in whether they do the apply computations in float or double as well.
