No popcnt compilation and/or makefile?

[rwbc]

Hi again, Volker

I see you are making good progress :) Would you mind adding a non popcnt compilation for older hardware and/or a simple makefile, then I could compile it myself? (Mainly using gcc/clang under msys2 - I never touch VC and I hate cmake, sorry)

Hi Guenther,

I added a version "_OLD_HW" not using hardware popcount and not using HW bit scan. It is about 20% slower than the version with hardware support. I optimized it a little to gain this result. I use the bitSanForeward by Kim Walisch, the Brian Kernighan version of pop count for sparcely populated bitboards and the SWAR Popcount by Donald Knuth for higher populated popcount.

Please give me an input, if this works for you and then I will close this issue. I will not forget to add a make file, but this will take a while.

Thanks Volker! You can close the issue now :) (see output from cmd below)
