  fix Issue 9404 - Nullable is unusable with 2.061

Now, user-defined but non identity opAssign is just ignored in identity assignment resolving.

For the identity assignment operation, following four operations might be defined by the compiler.

1. If a user-defined identity `opAssign` is defined, it is used.
2. If the struct has postbit constructor, "copy & swap" operation is used.
3. If member-wise assignment is necessary, it is used.
4. Otherwise, assignment possibility is calculated from bitwise assignable of whole members.

As a conclusion, except for the case where the members have disabled opAssign, identity assignment will succeed in almost cases.
