5; Same as the dynamic-alloca-lifetime.ll X86 test, which was used to fix a bug
6; in stack colouring + lifetime markers.

8; This test crashed in PEI because the stack protector was dead.
9; This was due to it being colored, which was in turn due to incorrect
10; lifetimes being applied to the stack protector frame index.
