    x86: Enable -fcf-protection with multi-byte NOPs

-fcf-protection no longer depens on -mcet and with revision 259522:

commit d59cfa9a4064339cf2bd2da828c4c133f13e57f0

    Define __CET__ for -fcf-protection and remove -mibt

-mcet becomes an alias for -mshstk.  Since all usages of -mcet and
-mno-cet have either been removed or replaced, we can remove the -mcet
command-lint option.
