Permute an 8x8 block according to permutation.

Parameters
blockthe block which will be permuted according to the given permutation vector
permutationthe permutation vector
lastthe last non zero coefficient in scantable order, used to speed the permutation up
scantablethe used scantable, this is only used to speed the permutation up, the block is not (inverse) permutated to scantable order!
