x86: Enable non-temporal memset for Hygon processors
This patch uses 'Avoid_Non_Temporal_Memset' flag to access
the non-temporal memset implementation for hygon processors.
Test Results:
hygon1 arch
x86_memset_non_temporal_threshold = 8MB
size new performance time / old performance time
1MB 0.994
4MB 0.996
8MB 0.670
16MB 0.343
32MB 0.355
hygon2 arch
x86_memset_non_temporal_threshold = 8MB
size new performance time / old performance time
1MB 1
4MB 1
8MB 1.312
16MB 0.822
32MB 0.830
hygon3 arch
x86_memset_non_temporal_threshold = 8MB
size new performance time / old performance time
1MB 1
4MB 0.990
8MB 0.737
16MB 0.390

For hygon arch with this patch, non-temporal stores can improve
performance by 20% - 65%.
