Refactor the SnoopPrecompile block and add nonlinear statements

[odow]

This takes the TTFX of Ipopt from 13 seconds to 4. We can attack the rest by adding a block to Ipopt.

@time using JuMP, Ipopt
@time @eval begin
  let
    model = Model(Ipopt.Optimizer)
    @variable(model, x >= 0)
    @variable(model, 0 <= y <= 3)
    @NLobjective(model, Min, (12x + 20y)^2)
    @constraint(model, c1, 6x + 8y >= 100)
    @constraint(model, c2, (7x + 12y)^2 <= 120)
    optimize!(model)
  end
end;
