438308b3a2 Rework benchmark mode and min/max range 
Was maybe my fault, but the benchmark mode was
always recomputing from nonce 0.

Also fix blake if -d 1 is used (one thread but second gpu)

stats: do not use thread id as key, prefer gpu id...

b128312efb cuda: store device SM in a global var 
sample usage made for blake and fugue (higher intensity for SM5.2)

add these to cuda_helper and clean unused code

5bc969fa57 Some work on data alignment 
linux: add -march=native (we build it ourself) and some other flags

+ remove unused vars (seen with -Wall)

93bb428bdf blake: rewrite the cache system 
Unlike other hash algos, blake256 compute the hash
with blocks of 64 bytes.

We can do the first part on the cpu, only the 4 last int32
are computed on gpu (including the tested nonce)

Previous method was also using this kind of cache with a crc.

Blake Hash Speed: +5%

91eea0d76b blake: remove int cudaMemcpyToSymbol for MSVC 
use clz (leading zeros) asm func for a fast gpu compare of ptarget[6]:[7]

add also missing windows ctz/clz host functions

New NEOS speed: 227MH to 270MH (Gigabyte 750Ti Black Edition)

de80c7e9d1 blake: remove unused parameter and fix index in d_hash 
that reduce the speed to 92MH/s but the next commit
give us 30 more

so, todo: merge the whole checkhash proc in gpu_hash
          and remove this d_hash buffer...
