The algorithm and its multiple variations below
below accumulates the norm by blocks of size "block_size".
Each block may span across multiple lines and it is
not necessary aligned by row boundaries. Within a block
the norm is accumulated to intermediate light-weight
type (worktype). It really makes sense for 8u, 16s, 16u types
and L1 & L2 norms, where worktype==int and normtype==int64.
In other cases a simpler algorithm is used
