Intel Control-flow Enforcement Technology (CET) is a
processor feature that blocks return/jump-oriented
programming (ROP) attacks.
It is currently only supported on Tiger Lake client
processors, but will be available on other processors
in the future.
CET requires toolchain support. gcc8 does support it.
For now, this will opt-in only at least until the
technology is available on server processors.
