If comp_mode is used the code will not compile.

- fix compile issue
- fix wrong conditions to handle `comp_mode`

OpenCL: fix Blake hashing

Windows driver creates wrong code if unroll is used.

OpenCL: fix work size message

CUDA: optimze cn_gpu auto suggestion

OpenCL: use algorithm names instead of number

add ryo algorithm fork

cuda: optimize cn-gpu

Fix message with the maximal allowed worksize if cryptonight_gpu is
used.

optimize the algorithm for cryptonight_gpu autosuggestion

switch with block 6 to cryptonigh_gpu

 - use precomuted indicies within the loop
 - `cn_explode_gpu` use all threads to load the state

Use the algorithm names from `cryptonight.hpp` instead if number within the OpenCL kernel.

fix cuda 10

- fix race condition during shared memory access
- optimize memory access

Implement CN-GPU Proof-of-Work Algo

- fix broken trutle coin

refactor POW selection algorithm

Avoid that we do multiple lookups to `std::map` to find the OpenCL
kernel binaries.

- add helper method `GetAllAlgorithms()` to get all active POW
algorithms
- select max scratchpad memory size based on the dev pool and user
algorithms

In the current implementation the POW algorithm in dev pool section of a
currency will not be taken into account during the binary creation.
This PR changes the behavior and allow to create binaries for more than two POW algorihms.
