nocf_check attribute can be used with -fcf-protection -mcet to disable control-flow check by adding NOTRACK prefix before indirect branch. When -mindirect-branch=thunk-extern -mindirect-branch-register is added, indirect branch via register, "notrack call/jmp reg", is converted to call/jmp __x86_indirect_thunk_nt_reg When running on machines with CET enabled, __x86_indirect_thunk_nt_reg can be updated to notrack jmp reg at run-time to restore NOTRACK prefix in the original indirect branch. Since we don't support -mindirect-branch=thunk-extern, CET and MPX at the same time, -mindirect-branch=thunk-extern is disallowed with -fcf-protection=branch and -fcheck-pointer-bounds.
