It is buggy in some Linux because the unique_ptr will be free however
the std::string trying to use that char*.

Moreover, it is no need to demangle for error log by Paddle.
Just use `c++filt` or other shell utilities to do this.

1. finish lookup table CPU and GPU kernel
2. Add some cuda helper
3. Add some math funtor

* Wrong Printf format before

* Should always use `dynload::` for cuda function.
* Fix cublas.h without DSO load.

Fix #3386

* Make `PADDLE_ENFORCE_EQ` supports custom class, like DDim

* fix some enforce

* remove compatible_type to avoid compile error

* remove shared_ptr

* fix tensor error msg
