1. Interpret EH actions properly …

   The EH actions stored in the LSDA follows the format of GCC except table
   (even for LLVM-generated code). An missing action in the table is the
   encoding for `Terminate`, see [1].
   
   The currently code interprets it as `None`, as a workaround for rust-lang#35011,
   an issue that seems to occur in LLVM 3.7 and not after 3.9. These are
   very old versions of LLVM and we don't support them anymore, so remove
   this workaround and interpret them properly.
   
   Note that LLVM currently does not emit any `Terminate` actions, but GCC
   does. Although GCC backend currently doesn't do unwinding, removing it
   preemptively would prevent future developers from wasting time to figure
   out what's wrong.
