Add avxifma feature detection on x86
Add avx-ifma detection according to the https://en.wikipedia.org/wiki/CPUID#EAX=7,_ECX=1:_Extended_Features.
@TianyouLi, could you add test from cpuid dump like this http://users.atw.hu/instlatx64/AuthenticAMD/AuthenticAMD0A70F52_K19_Phoenix_01_CPUID.txt
OctalCore AMD Ryzen 9 8700G (Phoenix, Zen4 APU, supported: AVX512F/CD/VL/BW/DQ/VNNI/IFMA/VAES/GFNI/VPCLMUL/BITALG/VPOPCNTDQ/VBMI/VBMI2/BF16)
It looks like this CPU supports IFMA

Hi @toor1245, sorry for the late response. Unfortunately I can not access the http://users.atw.hu/instlatx64/AuthenticAMD/AuthenticAMD0A70F52_K19_Phoenix_01_CPUID.txt, but I do see it from https://github.com/InstLatx64/InstLatx64/blob/master/AuthenticAMD/AuthenticAMD0A70F52_K19_Phoenix_01_CPUID.txt. Would it be possible to kindly let me know which tool I should use to dump the CPUID info as required? Thanks.

strange the qemu 7.1.0 in the trace, we should be in 9.0.2 IIRC

it is old message, so in the main branch it was fixed, maybe this branch need to rebase with main
Hi @toor1245, sorry for the late response.

if you have CPU that supports avxifma, you can use cpuid tool to dump:
cpuid -r -1
As for https://github.com/InstLatx64/InstLatx64/blob/master/AuthenticAMD/AuthenticAMD0A70F52_K19_Phoenix_01_CPUID.txt
This is also the same source so there is no difference. This is used on the site, so there is no difference in taking cpu dump from the GitHub repository or from the site
@toor1245 again, terribly sorry for the late response. I got the cpuid dump and try to add an unitest. Could you please kindly review and let me know your thoughts? Thanks.
