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%
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)

stratum: handle a small cache of submitted jobs
Prevent to send duplicated shares on some pools like hashharder..
This cache keeps submitted job/nounces of the last 15 minutes
so, remove exit on repeated duplicate shares,
the submitted cache now handles this problem.
