  Changed paths:
    M llvm/lib/Target/X86/X86IndirectBranchTracking.cpp
    M llvm/test/CodeGen/X86/indirect-branch-tracking-eh.ll
    A llvm/test/CodeGen/X86/indirect-branch-tracking-eh2.ll

  Log Message:
  -----------
  Handle CET for -exception-model sjlj

Summary:
In SjLj exception mode, the old landingpad BB will create a new landingpad BB and use indirect branch jump to the old landingpad BB in lowering.
So we should add 2 endbr for this exception model.
