v12.4:
- slightly improved speed for some cards (1-2%).
- added "-gmap" option.
- a few minor changes/improvements.
Perhaps 1% improvement on 470, hard to tell, bout 299 sol/s avg on 470 8gb, bios mod
Not all cards got speedup. My tests show most speedup for Tonga cards, some Hawaii cards, but speedup is minor anyway.
There is no difference for R9 Nano.
