cmd/compile: don't crash in size computation for invalid type An invalid program may produce invalid types. If the program calls unsafe.Sizeof on such a type, which is a compile-time computation, the size-computation must be able to handle it. Add the invalid type to the list of permissible basic types and give it a size of 1 (word). Fixes #52748.
