Quark and S3 are now a bit faster (+1 %)
x11 get +0.6 % (+20kH/s on a 750ti, +30kH on a 960)
80 bytes implementation to do/test ... (skein/skein2)
but keep my previous version for older devices...
5% improvement by the vshl asm swap functions, mixed shl+add inst.,
Add also xchg(x, y) func and XCHG(x, y) define in cuda_helper for later use...
other jh changes are mainly for the beauty of the code...

Implementation based on klausT work.. a bit different
This code must be placed in a common .cu file,
cuda.cpp is not compiled with nvcc and doesnt allow cuda code...
Seems to be djm34 work, i recognize the code style ;)
Code was cleaned/indented and adapted to my fork...
Only usable on the test pool until 16 december 2014!
Added to most algos, checkhash function scans a big range
and can find multiple nonces at once if the difficulty is low.
Stop ignoring them, submit second one if found...
Clean the draft code for rc=2 implemented for blake and pentablake
btw... fix the reduced displayed hashrate when a nonce is found...

Tested on x11 which find sometimes 3 nonces in one call,
actually they are ignored because only the biggest was kept...
This commit doesnt fix that, but will allow to enhance shares rate later...
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
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)
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
