This uses a new set of annoations viz. ENTRY_CFI/END_CFI to enabel cfi ops generation.
Note that we didn't change the normal ENTRY/EXIT as we don't actually want unwind info in the trap/exception/interrutp handlers which use these, as unwinder then gets confused (it keeps recursing vs. stopping). Semantically these are leaf routines and unwinding should stop when it hits those routines.
