Unwinding

[Kito Cheng]

Code for stack unwinding is using sspinc to update ssp, does it possible to use csrw for updating ssp directly?

[Ved Shanbhogue]

It is also possible to write the ssp directly but the unwind is recommended to follow the structure outlined to guard against unwinding past the bounds of the current shadow stack to another shadow stack of the program.
