[FIX] Alignement detection

For the SIMD vectorization it needs to be determined if a memory address lies points to an aligned address or not. This detection only worked for pointers depending on the inner loop counter so far.

test_alignment_and_correct_ghost_layers fails on SVE and RVV. Please fix. I assume this happens because we no longer generate the alignment check on these ISAs because they don't have separate aligned and unaligned load/store instructions. In this case, bypass the with pytest.raises(ValueError) if ast.instruction_set['loadA'] == ast.instruction_set['loadU'].

I saw that there are cases where loadA and loadU are similar and still the alignment check was performed (e.g. Neon instruction set). This is due to a fixed vector width. I now removed the alignment check for these architectures. Is this ok from your perspective?
