In this PR I add conversion methods to the SparseArrays stdlib which enable the conversion from
AbstractSparseMatrixCSCto the specialLinearAlgebramatrix typesDiagonal,Tridiagonal,SymTridiagonal,LowerTriangular,UpperTriangular. This has been brought up in JuliaLang/LinearAlgebra.jl#851.(cc @dkarrasch, @jishnub )
Close JuliaLang/LinearAlgebra.jl#851.
