Started optimizing some of the OpenCL kernel for latest AMD Catalyst 15.12:

- Replaced SBOX for DES:

replaced JtR's * Bitslice DES S-boxes making use of a vector conditional select operation (e.g., vsel on PowerPC with AltiVec).
with     JtR's * Bitslice DES S-boxes for x86 with MMX/SSE2/AVX and for typical RISC architectures.

Performance increased for DEScrypt from 355MH/s to 405MH/s and for LM from 11100MH/s to 12000MH/s

BTW, the same effect can be seen with non-maxwell GPU's

- Remove some volatile keywords no longer needed thanks to fixed catalyst bugs

- Fix weak-hash-check parameter for use with tools/test.sh
