[PATCH] D16572: PR23057: fix use-after-free due to local token buffer in ParseCXXAmbiguousParenExpression

I didn't introduce a leak because I pass ownership of the Buffer to EnterTokenStream (i.e. pass true as the last argument OwnsTokens). ASan also doesn't report a leak with my patch. Original code didn't have double free because it used call EnterTokenStream with OwnsTokens == false.
