CuSparse does not support broadcast

[ChrisRackauckas]

using CUDA
CUDA.allowscalar(false)
A = cu(sprand(100,100,0.1))
A .+ 2

Scalar indexing is disallowed.
Invocation of getindex resulted in scalar indexing of a GPU array.
This is typically caused by calling an iterating implementation of a method.
Such implementations *do not* execute on the GPU, but very slowly on the CPU,
and therefore are only permitted from the REPL for prototyping purposes.
If you did intend to index this array, annotate the caller with @allowscalar.

Similarly fill! doesn't work:

using CUDA
CUDA.allowscalar(false)
A = cu(sprand(100,100,0.1))
fill!(A,true)

Dup of #829. I'll have a look at this later this month.
