[LSDA] Take ttype_index into account when taking unwind action

If `cs_action != 0`, we should check the `ttype_index` field in action record. If `ttype_index == 0`, a clean up action is taken; otherwise catch action is taken.

This can fix unwind failure on AIX which uses LLVM's libunwind by default. IIUC, rust's LSDA is borrowed from c++ and I'm assuming itanium-cxx-abi https://itanium-cxx-abi.github.io/cxx-abi/exceptions.pdf should be followed, so the fix follows what libcxxabi does. See https://github.com/llvm/llvm-project/blob/ec48682ce9f61d056361c5095f21e930b8365661/libcxxabi/src/cxa_personality.cpp#L152 for use of `ttype_index`.
