Pengfei Wang 6a0d432e9e [X86] [CET] Deal with return-twice function such as vfork, setjmp when
CET-IBT enabled

Return-twice functions will indirectly jump after the caller's position.
So when CET-IBT is enable, we should make sure these is endbr*
instructions follow these Return-twice function caller. Like GCC does.
