Add a run-time branch in KokkosBlas::dot for 2-D Views where exactly one of the Views has a single column. We need this for trilinos/Trilinos#1013 .

KokkosBlas::dot: Add multivec*vec & vec*multivec cases
6f1d896 
Make KokkosBlas::dot work for the case of a multivector (multiple
columns) dot a vector (single column), and a vector (single column)
dot a multivector (multiple columns).  Both of these cases compute the
dot product of each column of the multivector, with the single vector.

This fixes kokkos/kokkos-kernels#13
and relates to #1013 .
