Missing CUDA kernels, and fix many warnings

@all

• Add missing herfb and tpmqt CUDA kernels
• Silent all warnings in Debug with gcc 5.4
• Replace max/min macros with static inline functions to avoid warnings about comparing unsigned/signed int and or int sizes.

@sylvand : can you tell me if you still have trouble when compiling with StarPU ? I hope, I removed every probems.
