suzerain: remove explicit unroll

Let the compiler decide what it wants to do here
as I originally added them sans benchmarking information.

suzerain: add 1+gamma scaling to final row

Adjusts gbdmv implementation to include a (1+gamma) scaling
factor on the final row using only constant space.  We pay
for more branches but the number of memory accesses remains
nearly identical.  Updates the BLAS-like wrappers to supply
gamma == 0 as a degenerate case as well as the tests.
