Daniel Martí ba6974fdc3 cmd/compile: fix crash on invalid struct literal
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.
