If one tries to use promoted fields in a struct literal, the compiler errors correctly. However, if the embedded fields are of struct pointer type, the field.Type.Sym.Name expression below panics. This is because field.Type.Sym is nil in that case. We can simply use field.Sym.Name in this piece of code though, as it only concerns embedded fields, in which case what we are after is the field name. Added a test mirroring fixedbugs/issue23609.go, but with pointer types. Fixes #26416.
