// Regression: zero-binding closure not wrapped in SSAMakeClosure.
//
// The SSA builder's buildFuncLit returned a bare *SSAFunction for function
// literals with zero captured variables. When this function was stored in a
// variable and called, the emitter tried extractvalue {ptr,ptr} on the
// loaded value, which was a ptr not {ptr,ptr}.
//
// Reproduces: function literal with zero free variables, stored and called.
// Fixed in: pkg/ssa/ssa_builder.mx (SSAFunction now always wrapped).
