Initial commit for porting SELL to GPU
- Add tiled SPMV and basic SpMVfor SeqSELL
- Tested in serial

- Use different slice
Initial commit for porting SELL to GPU
- Add tiled SPMV and basic SpMVfor SeqSELL
- Tested in serial
- Offloadmask is used to determine when the matrix should be copied to GPU
- Use different slice height for CUDA version
- By checking the nonzerostate, PETSc can decide if the whole matrix need to be copied or just the values need to be copied
- Make the convert function public so that the very slow MatConvert_Basic can be avoided sometimes. E.g. one can use a two-step convert method: AIJ->SELL,SELL->SELLCUDA instead of the direct convert AIJ->SELLCUDA
- Make the FLOPS count for SELL same as that for AIJCUSPARSE.
- MatDisAssemble is not needed.
- Change slice height from 32 to 16 for GPU
- To overlap communication with MatMult, VecScatterBegin() should be called before MatMult() for the diagonal part.
- SLICE_HEIGHT is defined to be 32 to match the warp size of GPU. For other cases, it is still 8.
