After this patch, we will generate the function body from implicitly instantiated class. This is important for consumers with same template arguments. Otherwise the consumers won't see the function body. Since the consumers won't instantiate the templates again if they find an instantiation. Also we will generate the variable definition if the variable is non-inline but known as constant. Such variables may not affect the ABI, but they may get involved into the compile time constant computation in the consumer's code. So we have to generate such definitions.
