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.
To enable shadow stack protection in a program, -fcf-protection=return
must be used to compile the program. -mcet/-mshstk are used to enable
shadow stack intrinsics to IMPLEMENT shadow stack, not to ENABLE shadow
stack protection. Since -mcet won't get any shadow stack protection,
-mcet will only lead user confusions. This set of patches removes -mcet
from GCC 8.
H.J. Lu (5):
x86/CET: Build target libraries with -mshstk
Regenerate configure of target libraries
Don't bootstrap GCC with -mcet
x86/CET tests: Remove -mcet/-mno-cet or replace -mcet with -mshstk
x86/CET: Remove the -mcet command-lint option
