In JuMP, what’s the function analogous to MathProgBase.numlinconstr(model) for getting the number of nonlinear constraints?

See [https://github.com/JuliaOpt/JuMP.jl/blob/272d54bd1305889e353d8109091c0544c681bfc9/src/JuMP.jl#L191](https://github.com/JuliaOpt/JuMP.jl/blob/272d54bd1305889e353d8109091c0544c681bfc9/src/JuMP.jl#L191). It’s a linear function of `numconstr`, `numlinconstr`, and `numquadconstr`.
