forward `fill!` for views of OffsetArrays?

[simeonschaub]

Would it be possible to forward fill!(a::SubArray{T, N, <:OffsetArray}, x) to fill!(view(parent(parent(a)), ...), x)? I'm having issues because I want to fill a view of an OffsetArray backed by a CuArray, but currently this tries to use the fallback definition in Base which requires scalar indexing.
