Log message:
Add _CET_ENDBR to amd64 coroutine code

I originally thought this issue was post-7.5, but after getting
access to a 7.5 machine with IBT, I confirmed it affects 7.5.

This fixes SIGILL/ILL_BTCFI for the following example code:

mutex = Mutex.new
mutex.synchronize { Fiber.new { mutex.owned? }.resume }

Thanks to tb@ for following up with me regarding this.
