CGBuiltin.cpp: Fix abuse of ArrayRef in EmitOverflowIntrinsic().
In ArrayRef<T>(X), X should not be temporary value. It could be rewritten more redundantly;
llvm::Type *XTy = X->getType();
ArrayRef<llvm::Type *> Ty(XTy);
llvm::Value *Callee = CGF.CGM.getIntrinsic(IntrinsicID, Ty);
Since it is safe if both XTy and Ty are temporary value in one statement, it could be shorten;
llvm::Value *Callee = CGF.CGM.getIntrinsic(IntrinsicID, ArrayRef<llvm::Type*>(X->getType()));
ArrayRef<T> has an implicit constructor to create uni-entry of T;
llvm::Value *Callee = CGF.CGM.getIntrinsic(IntrinsicID, X->getType());
MSVC-generated clang.exe crashed.
