This will allow later more gpu candidates.
Note: This is an unfinished work, we keep the previous behavior for now
To finish this, all algos solutions should be migrated and submitted nonces attributes stored.
Its required to handle the different share diff per nonce and fix the possible solved count error (if 1/2 nonces is solved).
also known as "Thor's Riddle"... yes sure ;)
Credits to ocminer who found and "implemented" it.
Note: tested "ok" on x64 and CUDA 6.5 x86, not on 7.5 and 8.0 x86
PS: Don't have the time for a more proper CUDA implementation of Streebog
