Please add documentation to docs/LanguageExtensions.rst for the
benefit of users and reviewers. Thanks in advance.

+  ArrayRef<llvm::Type *> type(X->getType());
+  llvm::Value *callee = CGF.CGM.getIntrinsic(IntrinsicID, type);
+  llvm::Value *tmp = CGF.Builder.CreateCall2(callee, X, Y);

Variable names should start with an uppercase letter.
