New Revision: 72031

URL: http://llvm.org/viewvc/llvm-project?rev=72031&view=rev
Log:
Include StmtNodes.def to declare Visit methods for all of the known
kinds of statements (in the instantiation logic). No functionality
change, but now we'll get linker errors if we add a statement but
forget to introduce its instantiation logic.
