x86: Add IBT/SHSTK bits to cpu-features
Add IBT/SHSTK bits to cpu-features for Shadow Stack in Intel Control-flow
Enforcement Technology (CET) instructions:
https://software.intel.com/sites/default/files/managed/4d/2a/control-flow-enforcement-technology-preview.pdf
* sysdeps/x86/cpu-features.h (bit_cpu_BIT): New.
(bit_cpu_SHSTK): Likewise.
(index_cpu_IBT): Likewise.
(index_cpu_SHSTK): Likewise.
(reg_IBT): Likewise.
(reg_SHSTK): Likewise.
* sysdeps/x86/cpu-tunables.c (TUNABLE_CALLBACK (set_hwcaps)):
Handle index_cpu_IBT and index_cpu_SHSTK.
