Added and using a helper function `isCIE` to avoid using the error return path from `decodeFDE`.

Technically, the decision between a full section and a plain FDE probably should be outside of `_unw_add_dynamic_fde`, in `__register_frame` in `UnwindLevel1-gcc-ext.c`. That'd require adding a C wrapper for `isCIE` in `libunwind.cpp` though.
