示例1: visitIntrinsic
///
/// Method: visitIntrinsic()
///
/// Description:
/// Generate correct DSNodes for calls to LLVM intrinsic functions.
///
/// Inputs:
/// CS - The CallSite representing the call or invoke to the intrinsic.
/// F - A pointer to the function called by the call site.
///
/// Return value:
/// true - This intrinsic is properly handled by this method.
/// false - This intrinsic is not recognized by DSA.
///
