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%
based on klaus commits, will increase a bit speed of most algos
PS: main increase is due to the register count tuning in Makefile
and for skein512 on linux, its the ROTL64
but almost no changes on X11 : 2648MH/s vs 2630 before
Indent, and put commonly used functions proto. in cuda_helper.h
And add them to --cputest function
Also change the color option to --nocolor, -C is no more needed
