c181978d7c fix(arm): Updated arm cortex status (#209) 
* Cortex A8 Vulnerable

Arm Cortex A8 is vulnerable to variants 1 & 2  (https://developer.arm.com/support/arm-security-updates/speculative-processor-vulnerability)

Part number is 0xc08 (https://developer.arm.com/docs/ddi0344/b/system-control-coprocessor/system-control-coprocessorregisters/c0-main-id-register)

False negative reported by @V10lator in #206

* ARM Cortex A12 Vulnerable to 1&2

https://developer.arm.com/support/arm-security-updates/speculative-processor-vulnerability

* A76 vulnerable to variant 4

All arch 8 cortex A57-A76 are vulnerable to variant 4.

https://developer.arm.com/support/arm-security-updates/speculative-processor-vulnerability

* Whitelist variant4 nonvuln Arms

* ARM Cortex Whitelist & Cumulative Blacklist

Applies all information about vulnerabilities of ARM Cortex processors (from https://developer.arm.com/support/arm-security-updates/speculative-processor-vulnerability).

Whitelist & blacklist approach, using both vulnerable and non vulnerable status for each identified CPU, with vulnerabilities tracked cumulatively for multi CPU systems.

5962d20ba7 fix(variant4): whitelist from common.c::cpu_no_spec_store_bypass (#202) 
* variant4 from common.c::cpu_no_spec_store_bypass

Variant 4 - Add function to 'whitelist' the hand-full of CPUs unaffected by speculative store bypass. 

This would allow improved determination of variant 4 status ( #189 ) of immune CPUs while waiting for the 4.17/stable patches to be backported to distro kernels.

Source of cpu list : https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/arch/x86/kernel/cpu/common.c#n945)
Modeled after is_cpu_specex_free()

* amd families fix

amd families are reported by parse_cpu_details() in decimal

* remove duplicates

Only list processors which speculate and are immune to variant 4.
Avoids duplication with non-speculating CPUs listed in is_cpu_specex_free()

7e4899bcb8 ibrs can't be enabled on no ibrs cpu (#195) 
* ibrs can't be enabled on no ibrs cpu

If the cpu is identified, and does not support SPEC_CTRL or IBRS, then ibrs can't be enabled, even if supported by the kernel.
Instead of reporting IBRS enabled and active UNKNOWN, report IBRS enabled and active NO.

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.
