Title: Issue 9077 - Struct copy constructor ignored when opAssign with a different type is present

http://d.puremagic.com/issues/show_bug.cgi?id=9077

As I commented in `StructDeclaration::buildOpAssign`, even if user-defined non-identity opAssign exists, built-in identity opAssign is defined implicitly.

I cannot sure that this is just one exception. (For example, should opEquals be treated same as?)
