gollvm: handle more circular function type conversions

Handle another case of circular function types in
convertForAssignment, where LHS and RHS are two different
representation of the same circular function type, i.e.
LHS is *function, whereas RHS is *CFT.

This case is triggered with code like

type fs []f
type p struct { t fs }
type f func(*p) bool

func (s *fs) pop() (i f) {
	i = (*s)[0]
	return i
}
