- Move ExprIterator to Stmt.h so that it can be used by classes defined in Stmt.h

- Implement child_begin() and child_end() for AsmStmt.  Previously these had stub implementations that did not iterate over the input/output operands of an inline assembly statement.
- Use ExprIterator for performing iteration over input/output operands.
