22cae605e1 fix(retpoline): remove the "retpoline enabled" test 
This test worked for some early versions of the retpoline
implementation in vanilla kernels, but the corresponding
flag has been removed from /proc/cpuinfo in latest kernels.
The full information is available in /sys instead, which
was already implemented in the script.

0267659adc cleanup: remove superseded atom detection code 
This is now handled properly by checking the CPU
vendor, family, model instead of looking for the
commercial name of the CPU in /proc/cpuinfo

247b176882 feat: detect known speculative-execution free CPUs 
Based on a kernel patch that has been merged to Linus' tree.
Some of the detections we did by grepping the model name
will probably no longer be needed.

aa18b51e1c fix(variant1): smarter lfence check 
Instead of just counting the number of LFENCE
instructions, now we're only counting the those
that directly follow a jump instruction.
