Gary Guo 8bda13367e 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 #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.
