My testing with removed  `@requires vm.flagless` finished and actually all these tests passed. 
Note, I did not test this PR. I just removed `vm.flagless`. 

So my hypothesis about using SSE and AVX flags to catch these tests failures is incorrect.  We need to find an other solution.

@pfustc I think we can leave `vm.flagless` as it is based on my experiment.
