It is possible for a shader to declare two plain struct types which simply share the same OpName without there being an implicit value/buffer alias relationship. For to_member_name(), make sure to use the type alias master when resolving member names. The member name may be different in a type alias master if the SPIR-V is being intentionally difficult.
